Cisco Collegue leaving need to secure ADMIN account

[ITBASIC2010]

Hi Everyone and great to join this forum, looks like many experts on here so hopefully someone can help me with a Cisco ASA querrie.

A collegue at my workplace is living and I need to ensure that the cisco ASA 5510 is secured and remote access for him is removed, now I now that i can just disable-delete his username using the ASDM but wonder what will happen if I delete -reset the main admin accont and also there is a enable_15 account that is not attached to any VPN group Policy or VPN group lock? is the Enable_15 the default admin account? do you suggest I call in the professionals and outsource this to a Cisco expert as I have limited knowledge on the ASA 5510? Thank you for your help.

you can safely change any account on the device. just make 100% sure that you verify the changes before closing your current session meaning open a second session (either ssh or https) to the device and try to sign in with the new credentials.
