NSX-T Password Expiration

NSX-T has a default password expiration policy of 90 days for NSX-T Manager and NSX-T Edges. As soon as this expiration period passes, at the login page of NSX-T Manager an error appears complaining that “Your password has expired”. As a result, you are not able to login to NSX-T Manager.

To solve this issue, login to NSX Manager’s virtual appliance through SSH. Enter admin as the username and use current password to login. After login in NSX Manager, you will be asked to change your password because it is expired. This is the way you can reset NSX Manager admin’s password.
