Employee Identities: Old Targets, New Scale
AI has changed the economics of identity attacks. Phishing, credential stuffing, social engineering, help desk impersonation, and MFA bypass attempts can now be generated, personalized, and scaled faster than human security teams can respond.
In 2026, every leftover password, weak recovery path, shared credential, and MFA coverage gap is no longer just a “legacy issue”, but a considerable vulnerability in identity security.
In the face of this changing landscape, most enterprises have made progress. They have SSO for SaaS, MFA for many apps, passkeys for selected workflows, PAM for privileged access, and other identity protections for high-risk accounts. But passwords still survive in the places that are hardest to modernize: legacy applications, Windows and Mac login, VPNs, protocols such as RDP/SSH/VDI, and shared or admin accounts.
That is why passwordless is back at the center of the identity security conversation. Not as a convenience project. Not as a SaaS-only upgrade. But as a way to retire identity security debt before AI turns it into enterprise-scale risk.
ZeroPassword™ technology was built for that job: eliminating user-managed workforce passwords across the full enterprise stack, including legacy systems that still require passwords on the backend.
The Identity Security Technical Debt
Security and IT teams, especially in legacy-heavy and highly-regulated industries, should consistently address all authentication weaknesses that were once accepted as exceptions but became permanent parts of the enterprise threat landscape. In this context the 2026 AI challenge is also an opportunity to once and for all fix the gaps that AI-powered attackers might exploit.
| Identity security debt | Why it matters |
|---|---|
| Legacy passwords | AI makes phishing, credential stuffing, and password attack campaigns cheaper and easier to scale. |
| MFA coverage gaps | Attackers look for systems where MFA is missing, inconsistent, or easier to bypass. |
| Password fallbacks | A passwordless front end can still fail if reset, recovery, or fallback flows remain phishable. |
| Shared credentials | Shared passwords create accountability gaps and increase social-engineering risk. |
| Legacy and on-prem systems | Older systems often sit outside SaaS SSO, passkey, and modern IAM programs. |
| Help desk reset flows | AI-generated voice, text, and identity impersonation make manual verification harder and create serious new attack vectors. |
| Disconnected environments | Cloud-first passwordless may not cover systems that cannot always reach cloud authentication. |
The Two Questions Every MFA Buyer Should Ask in 2026
Most vendor comparisons focus on authentication methods: push, OTP, passkeys, FIDO2, smart cards, biometrics, or device trust.
Those details matter, but they represent a superficial view of the problem. The better framework below examines this :
| Evaluation Aspect | Question to ask | Why it matters |
|---|---|---|
| Coverage scope | Where does the solution work? | Password risk often remains outside SaaS and SSO: legacy apps, endpoints, remote access, infrastructure, shared accounts, and disconnected environments. |
| Passwordless strength | Are user-managed passwords removed or just hidden? | If users still choose, type, and reset passwords, all password-related attack vectors remain. A partial passwordless solution can even increase the threat if passwords are used but forgotten more often. |
The 2026 Passwordless Market Map
Almost every major identity vendor can now claim some form of passwordless capability, support using passkeys, and brag about being phishing-resistant in some places. This can make the issue confusing even for the most sophisticated enterprise buyers.
Asking one question can help speed up things for decision makers: which part of identity security debt does each technology address?
| Category | Example vendors | What it helps with | What debt remains |
|---|---|---|---|
| IAM and IdP platforms | Microsoft Entra ID, Okta, Ping Identity | SSO, federation, access policy, SaaS identity workflows, adaptive access | Passwords in non-SSO apps, endpoints, legacy systems, and password recovery paths |
| MFA platforms | Cisco Duo, RSA ID Plus, Okta Verify, Microsoft Authenticator | Stronger verification across more access paths such as workstations and some legacy apps | User-managed passwords still exist everywhere. Phishing, fallback or recovery paths are a major risk. |
| Passkey and FIDO authenticators | Yubico, HID, Thales | Strong phishing-resistant authentication for supported workflows, mostly web apps | Coverage may be limited to systems that support passkeys, FIDO2, or WebAuthn |
| Identity protection and PAM platforms | CyberArk, Silverfort, BeyondTrust, Delinea | Privileged access, credential control, session monitoring, service-account protection, lateral movement reduction | Broader workforce passwords may remain outside privileged or monitored workflows, in 2026 “privileged accounts” is a dated concept |
| SDO ZeroPassword™ | Secret Double Octopus | Patented technology for eliminating user-managed passwords across modern, legacy, on-prem, remote, desktop, shared-account, and disconnected environments | Designed to offer strong phishing resistant MFA across the whole IT stack, and retire password-based identity debt |
What Major Solution Categories Do Well
IAM and IdP Platforms
IAM and IdP platforms are often the enterprise identity control plane. They manage users, access policies, federation, SaaS SSO, and adaptive access.
Microsoft Entra ID enables a passwordless authentication user experience through Windows Hello for Business, but this isn’t really aboput eliminating passwords. The same user-selected credential is stored in place and continues to be a threat.
Okta FastPass is a passwordless authenticator for all Okta-protected apps on supported platforms, using strong public-key cryptography through Okta Verify, but still suffers from incomplete coverage and reliance on phishable user-managed credentials.
MFA Vendors
MFA platforms reduce risk by adding verification beyond the password. Cisco Duo, for example, uses passkeys, platform authenticators, security keys, or Duo Push to secure web-based application access. It supports SAML and OIDC applications and some forms of remote access workflows, but is considered an outdated technology.
Standard MFA is not only partial in its’ coverage, it is also hiding the most serious identity threat – If the user still has a password, the organization still has password risk. MFA may reduce risk, but it does not necessarily remove the password attack surface.
Passkey and FIDO Authenticators
Passkeys and FIDO2 are among the strongest authentication methods available for supported use cases. They are especially powerful for phishing-resistant authentication in modern web and platform workflows. But passkeys are an authentication method, not a complete enterprise password-elimination strategy. A passkey can protect a modern web application. It may not automatically solve Windows login, Mac login, VPN, RDP, SSH, legacy apps, shared accounts, on-prem infrastructure, or offline access.
The question is not whether passkeys are strong, but whether the enterprise can apply passwordless authentication everywhere passwords still exist. And the answer is that it can’t, at least by using FIDO’s native capabilities. ZeroPassword™ can expand the scope of FIDO keys to everything that’s not natively supported, but many still fear the costs of physical cryptographic tokens, and cannot fully trust BYOD passkeys.
PAM and “Identity Security” Platforms
These vendors’ goal is to help secure privileged access and admin workflows, since these are considered very high-risk identity paths. But their approach, which splits employees’ identities into high- and low-risk categories, is increasingly being challenged.
Companies like CyberArk, Silverfort, and BeyondTrust, position their passwordless capabilities around protecting the workforce via a complex set of authentication methods, detection capabilities, and risk analysis across on-prem, cloud, and hybrid environments, but aren’t able to solve the identity security technical debt for the large majority of employees and workflows.
These platforms justify their high price tag by promoting features like vaulting and advanced monitoring, especially for privileged and high-risk accounts, but the key distinction remains: they cannot eliminate passwords for the broader workforce.
Why Passwordless UX Is Not the Same as Password Elimination
A login flow can look passwordless while passwords still exist underneath.
That matters because attackers do not care whether the interface looks modern. They care whether a reusable secret still exists.
| Maturity level | What it means | Risk that remains |
|---|---|---|
| Password + MFA | User enters a password, then completes MFA | Passwords can still be phished, stolen, reused, reset, or attacked |
| Passwordless front end | User sees a passwordless login flow, but passwords remain underneath or as fallback | Passwords still exist as an attack path |
| Phishing-resistant authentication | Authentication uses cryptographic, device-bound, or possession-based methods | Coverage may be limited to supported apps, devices, or workflows |
| SDO ZeroPassword™ | User-managed passwords are removed from the authentication workflow across modern and legacy systems | Password-based identity debt is reduced at both the user experience layer and the underlying credential layer |
This is where SDO’s patented ZeroPassword™ technology creates a sharper distinction. It is not just another MFA factor or passkey workflow. It is designed to eliminate user-managed passwords across the full enterprise environment. SDO states that its patented ZeroPassword™ technology replaces directory and legacy credentials with machine-generated ephemeral tokens, granting secure access to systems that still require passwords on the backend without requiring costly redesign. (Secret Double Octopus)
Why ZeroPassword™ Wins on Both Scope and Depth
Traditional MFA and partial passwordless improve authentication. But they often leave user-managed passwords in place or limit coverage to modern apps.
SDO ZeroPassword™ is designed to excel on the two dimensions that matter most in 2026: scope and depth.
| Dimension | Traditional MFA / partial passwordless | SDO ZeroPassword™ |
|---|---|---|
| Scope | Often strongest for SaaS, SSO, web apps, IdP-integrated workflows, or selected privileged paths | Extends passwordless across SaaS, legacy apps, on-prem systems, endpoints, VPN, RDP, SSH, VDI, shared accounts, and disconnected environments |
| Depth | May still rely on user-managed passwords, fallbacks, recovery flows, or backend credentials | Removes user-managed passwords from the workflow so there is no password for users to know, type, share, phish, reset, or rotate |
| Legacy support | Often limited to modern protocols such as SAML, OIDC, FIDO2, or WebAuthn | Supports systems that still require passwords on the backend by replacing them with ephemeral tokens |
| Deployment model | May require app modernization, protocol support, or ecosystem alignment | Works with existing directories, apps, and identity infrastructure |
| AI-era value | Reduces some attack paths but does not completely eliminate credential risk | Retires password-based identity debt before AI can exploit it at scale |
In the AI era, this distinction matters. If a password still exists for a user to know, type, reset, share, or fall back to, it remains identity security debt.
Where Passwords Usually Remain
Most passwordless projects start with SaaS. The harder work is everything else.
| Environment | Why passwordless often breaks down |
|---|---|
| Windows and Mac login | Endpoint login is not always covered by SaaS-focused passwordless tools |
| VPN | Remote access often still depends on password + MFA |
| RDP and SSH | Admin and infrastructure access can remain password-based |
| VDI and Citrix-style workflows | Authentication flows may be layered and inconsistent |
| Legacy applications | Many do not support SAML, OIDC, WebAuthn, or modern passwordless natively |
| On-prem infrastructure | Older systems often remain tied to AD, LDAP, RADIUS, or local credentials |
| Shared accounts | Password sharing creates audit, accountability, and reset problems |
| Disconnected or air-gapped environments | Cloud-first authentication may not be available or reliable |
That is the difference between passwordless for selected workflows and password elimination across the enterprise.
How to Evaluate Passwordless in 2026
A serious enterprise passwordless strategy should be evaluated against identity security debt, not just authentication methods.
| 2026 evaluation question | Why it matters |
|---|---|
| Does it remove phishable credentials, or only add stronger authentication? | AI-powered phishing and social engineering make leftover passwords more dangerous. |
| Does it cover recovery and fallback flows? | Attackers often bypass strong login by targeting reset and recovery paths. |
| Does it cover legacy and non-SaaS systems? | Passwordless programs often fail where systems cannot support modern protocols natively. |
| Does it reduce help desk dependency? | AI voice, video, and text impersonation increase risk in manual verification workflows. |
| Does it support shared and admin accounts? | Shared credentials create accountability gaps and high-value targets. |
| Does it work with existing IAM, MFA, and PAM investments? | Most enterprises need to pay down identity debt without ripping out the stack. |
| Does it prove enforcement across the full environment? | Compliance and audit teams need evidence, not just policy intent. |
Bottom Line
In 2026, passwordless is not about modernizing login, it is about retiring identity security debt before AI weaponizes it. MFA, IAM, passkeys, PAM, and identity protection all play important roles. But they are not equivalent to eliminating user-managed passwords everywhere the workforce authenticates.
SDO’s patented ZeroPassword™ technology is built to remove user-managed passwords across both dimensions that matter:
- Scope: legacy to cloud, including SaaS, endpoints, VPN, RDP, SSH, VDI, shared accounts, on-prem systems, and disconnected environments.
- Depth: no password for the user to know, type, share, phish, reset, rotate, or fall back to.
FAQ
What is passwordless authentication?
Passwordless authentication lets users log in without typing a traditional password. It can use methods like passkeys, FIDO security keys, biometrics, smart cards, mobile push, QR codes, or other strong authentication methods.
But not every “passwordless” experience actually removes passwords. Some solutions hide the password from the login screen while passwords still exist behind the scenes, in legacy systems, directories, fallback flows, or help desk reset processes.
ZeroPassword™ goes further. It is designed so users do not know, type, reset, rotate, copy, or share passwords at all. The goal is not just a better login experience. The goal is to eliminate user-managed passwords from the enterprise.
Why is passwordless more urgent in 2026?
AI is making identity attacks faster, more targeted, and easier to scale. Phishing emails, fake login pages, social engineering, help desk impersonation, and credential attacks are becoming harder for users and IT teams to spot.
Advanced AI-enabled threats also make old identity weaknesses more dangerous. Attackers do not need every system to be vulnerable. They only need one leftover password, one weak recovery flow, one MFA gap, or one legacy system that still depends on credentials.
That is why ZeroPassword™ matters now. It removes the password from the user’s hands, so there is less for attackers to phish, steal, reuse, or manipulate users into revealing.
What is identity security technical debt?
Identity security technical debt is the buildup of password and authentication problems that organizations never fully modernized.
It includes old passwords, password fallbacks, MFA gaps, shared credentials, weak reset processes, and systems that sit outside SSO.
This debt creates real business problems. It increases cyber risk, frustrates users, creates more help desk tickets, slows IT teams down, and makes compliance harder to prove.
ZeroPassword™ helps reduce that debt by removing user-managed passwords across the enterprise — including the systems that are usually hardest to modernize.
What is ZeroPassword™?
ZeroPassword™ is Secret Double Octopus’ patented technology for eliminating user-managed passwords across the enterprise.
It is designed so users never know or handle passwords. They authenticate with strong methods, while ZeroPassword™ handles access behind the scenes — even for legacy systems that still require credentials on the backend.
That means no passwords for users to remember, type, reset, rotate, copy, or share.
The benefits are straightforward: fewer phishing paths, fewer password reset tickets, less IT overhead, lower support cost, better user experience, and stronger compliance readiness.
How is ZeroPassword™ different from MFA?
MFA adds another step to the login process. A user may still enter a password, then approve a push notification, enter a code, or use another factor.
That is better than password-only login, but the password still exists.
ZeroPassword™ removes the user-managed password from the workflow. Users do not know the password. They do not type it. They do not reset it. They do not share it. They do not rotate it.
MFA asks, “How do we protect the password?”
ZeroPassword™ asks, “Why should the user have a password at all?”
Are passkeys the same as ZeroPassword™?
No. Passkeys are a strong passwordless method for modern apps and websites that support them.
But passkeys do not automatically remove passwords from the rest of the enterprise. They usually work best for modern SaaS and web applications. They do not, by themselves, eliminate passwords from VPN, RDP, SSH, Windows or Mac login, shared accounts, on-prem systems, or older applications.
ZeroPassword™ is broader. It is designed to eliminate user-managed passwords across both modern and legacy environments, including places where passkeys are not natively supported.
How is ZeroPassword™ different from Okta FastPass?
Okta FastPass is strong for Okta-protected apps and modern Okta-integrated workflows.
ZeroPassword™ focuses on a broader problem: eliminating user-managed passwords across the full enterprise, including systems that often sit outside modern SSO.
That includes legacy apps, Windows and Mac login, VPN, RDP, SSH, VDI, shared accounts, on-prem systems, AD-based environments, non-SAML applications, and disconnected environments.
The difference is scope and depth. FastPass helps with passwordless access where Okta controls the flow. ZeroPassword™ is designed to remove user-managed passwords wherever they remain.
How is ZeroPassword™ different from Microsoft Entra passwordless?
Microsoft Entra offers strong passwordless options, especially for Microsoft-centered environments.
But many enterprises are not purely Microsoft or fully modernized. Passwords can still remain in legacy apps, non-Microsoft systems, on-prem infrastructure, shared accounts, remote access workflows, fallback paths, and disconnected environments.
ZeroPassword™ is designed for that mixed reality. It extends passwordless authentication beyond modern Microsoft workflows and removes user-managed passwords across heterogeneous enterprise environments.
The goal is not just passwordless for supported Microsoft use cases. The goal is no user-managed passwords anywhere.
How is ZeroPassword™ different from Duo Passwordless?
Duo Passwordless is strong for supported web-based applications and Duo-protected access flows.
ZeroPassword™ is focused on broader password elimination. It is designed to remove user-managed passwords across SaaS, legacy apps, on-prem systems, Windows and Mac login, VPN, RDP, SSH, VDI, shared accounts, infrastructure access, and disconnected environments.
The difference is that Duo helps strengthen supported login flows, while ZeroPassword™ is designed to eliminate the user-managed password from the enterprise authentication workflow.
How is ZeroPassword™ different from PAM or identity protection platforms?
PAM and identity protection platforms are important for privileged access, admin accounts, service accounts, credential vaulting, session monitoring, and high-risk activity.
But they are usually not built for simple, broad rollout to every workforce user. PAM can also be costly and complex when used beyond privileged access.
ZeroPassword™ is designed for workforce-wide password elimination. It removes user-managed passwords from everyday authentication, not just privileged workflows.
In many organizations, PAM and ZeroPassword™ can work together. PAM protects privileged access. ZeroPassword™ removes user-managed passwords from the broader workforce.
What should enterprises look for in a passwordless solution?
Enterprises should look beyond the login screen.
A strong passwordless solution should remove user-managed passwords, not just reduce password prompts. It should work across SaaS, legacy apps, desktops, VPN, RDP, SSH, shared accounts, on-prem systems, and disconnected environments. It should also work with the identity tools and authenticators the organization already uses.
For 2026, the standard should be higher:
No user-managed credentials anywhere.
That is the ZeroPassword™ advantage — eliminating passwords across both the modern and legacy parts of the enterprise before AI-powered attackers can exploit what is left behind
