Question

Can I disable concurrent logins for users in Azure B2C application?

Hi all,

We have an introduced compliance requirement whereby users are only allowed to have a single session logged in at any one point in time (across browsers, devices etc). Does AD B2C allow for this?

Azure AD B2C doesn't have a built-in feature to enforce “single active session” across all devices and browsers. By default, B2C issues tokens that remain valid until they expire, and there’s no native mechanism to revoke other sessions when a new login occurs. You would likely need to implement server-side checks in your app to enforce single session per user.
