FAQ

Do I need to migrate my users off Azure AD B2C?

No. Authsignal connects to your Azure AD B2C tenant via OIDC custom policies. Your user directory, sessions, and existing policies all stay in place. Authsignal adds capabilities on top — it doesn't replace anything underneath.

What happens when Microsoft transitions Azure AD B2C to Entra External ID?

Authsignal's authentication layer is independent of the underlying IdP. If Microsoft transitions your tenant to Entra External ID, Authsignal continues to work. Your authentication policies, passkey enrollments, and rules engine configuration are preserved regardless of what happens underneath.
