Exclusive sign-in

Allow only one active session per user per application.

Exclusive sign-in limits each user to one active session per application. A new sign-in from another device or browser ends all previous sessions for that user and application.

Configuration

On the application edit page, enable Enable exclusive signin. The setting applies to all users of that application.

Behavior

On sign-in with exclusive sign-in enabled:

  • All existing sessions for that user and application are removed
  • A new session is created for the current sign-in
  • The user is effectively signed out everywhere else for this app

Example: user signs in on a laptop, then on a phone — the laptop session is terminated; only the phone session stays active.

When to use it

Exclusive sign-in reduces the risk of concurrent use of the same account (e.g. after forgetting to sign out on a shared PC). It also limits concurrent sessions per user. Users who need to stay signed in on multiple devices will have to sign in again when they switch.

How it works

For each sign-in with exclusive sign-in on: Hanzo IAM finds all sessions for that user and application, deletes them, creates a new session, and keeps only that session ID. This is done per application.
