TL;DR: Credential-based attacks keep MFA mandatory, while passkeys, adaptive policies, and AI agent access are reshaping what teams need from authentication providers, according to WorkOS. The real decision is no longer second-factor coverage alone, but whether the MFA layer fits enterprise identity, session control, and machine identity governance.
Editorial analysis by NHI Mgmt Group, based on content published by WorkOS: “Top 5 MFA providers for securing your app in 2026”.
Key questions
Q: What breaks when MFA is added late to a game login flow?
A: Late MFA usually exposes assumptions in the login architecture, especially around callback handling, token exchange, and how user state is restored after verification.
Q: Why do passkeys matter more than traditional second factors for app security?
A: Passkeys reduce reliance on reusable secrets and make phishing far harder because the credential is bound to the device and origin.
Q: How should app teams choose an MFA provider for B2B SaaS?
A: Choose the provider that fits your identity architecture, not just your login screen.
Practitioner guidance
- Map authentication methods to actual threat models Prioritise passkeys and other phishing-resistant options for user groups exposed to targeted attacks, and keep TOTP only where migration or compatibility requires it.
- Design MFA around tenant policy, not a single global rule Support per-organization enforcement, guest access handling, and enterprise federation so customer policy can differ without forcing a second auth stack.
- Treat session revocation as part of the auth control Require server-side session management or equivalent revocation capability so compromised accounts can be contained without waiting for tokens to age out.
Bottom line: The core MFA question in 2026 is no longer whether a second factor exists, but whether the provider fits enterprise identity, per-tenant policy, and modern session control.

MFA is no longer just a human authentication control: The article correctly shows that app teams now have to think about humans, service access, and AI agents in the same authentication architecture. That is where many programmes break, because login controls designed for people do not automatically govern non-human access paths. The practitioner conclusion is that MFA strategy now sits inside broader identity architecture, not beside it.
A few things that frame the scale:
- Across one million observed logins, 1 in 4 were password-based rather than SSO, 2 in 5 were not protected by MFA and 1 in 5 used a weak, breached or reused password.
A question worth separating out:
Q: How should security teams handle AI agents and other non-human actors in MFA planning?
A: Treat them as a separate identity class with their own credentials, scope, and revocation rules. Interactive user MFA does not map cleanly to agentic or machine workflows, so teams need token governance, step-up for sensitive actions, and explicit offboarding for non-human access.
