Require Password Change at Next Logon

If a user's identity source is the internal database, you can force the user to change his or her password the next time the user logs on. As an alternative, you can specify a new password for the user yourself. The new password must meet the requirements defined by the password policy for the user's security domain.

Procedure 

1. In the Security Console, click Identity > Users > Manage Existing.

2. Use the search fields to find the user that you want to edit. Some fields may be case sensitive. For more information, see Search Fields That Are Not Case Sensitive.

3. Click the user that you want to edit, and select Edit.

4. Select Force Password Change.

5. Click Save.
