resetting lost/forget admin and root password on F5 BIG IP

Perhaps you have another account with full admin rights you can still use? This would suffice to update the root and admin account passwords.

If not, check out section "Resetting a lost or forgotten root password" @ https://support.f5.com/kb/en-us/solutions/public/3000/300/sol3350.html

Once you have the root account access, you can normally set the admin password to anything you want in TMSH (i.e.

tmsh modify auth user admin password NewPasswoRd

). Only problem is that once you do that, you may have to re-configure the HA cluster. Put your standby appliance to Forced Offline state before you begin to ensure no unintended cluster failovers can occur as the cluster breaks.

First to reset the lost passwords you can go into the /config/bigip_user.conf file and change the "encrypted-password" field to password yourTempPassword. After you do that you can then load it via tmsh load sys config user-only. Once you do that, you can then change them in the GUI to something permanent so it re-encrypts them in the config file.

 

In an HA scenario, those accounts should sync with each other so no need to make them the same ahead of time.

Hi San, You should be able to go to ask.f5.com and query your request about password recovery.
