Working with Shared-Secret Lifecycle

Describes the procedure work with shared-secret lifecycle

All users of appliance two factor authentication get a shared-secret for verification. This shared-secret for a user remains in the two factor authentication group list until it is manually deleted. Even if a user becomes ineligible to access the system, the username remains linked to the shared-secret.

This exception is valid for those users opting for per-user authentication.

If the same user or another user with the same name is again added to the system, then the user becomes eligible to use the already existing shared-secret.

To prevent this exception, ensure that an ineligible user is manually removed from the Two Factor Authentication group.

Revoking Shared-Secret for the User

The option to revoke shared-secret is useful when user needs to switch to another mobile device or the previous shared-secret cannot be retrieved from the earlier device.

Perform the following steps to revoke shared-secret for the user:

  1. On the Appliance Web UI, navigate to Settings > Security > Two Factor Authentication.

  2. Ensure that the Enable Two-Factor-Authentication and Automatic per-user shared-secret checkbox are checked.

  3. Inspect Users Shared Secrets area to identify user account to revoke.
    You can revoke users who have already logged in to the Appliance.

  4. Click Revoke.

    Revoke Shared-Secret

  5. Select the user to discard by clicking the checkbox next to the username.

  6. Click Apply to save the changes.
    A new shared-secret code will be created for the revoked user and is presented upon the next login.
