According to the config. guide, this is the procedure for resetting the admin password:
If you forget the password for the admin user, another user with CLI Configuration permissions can log in and change the password.
If there are no other users with the required permissions, you can reset the admin password from the ASA. The default password differs based on software release; see Defaults for ASA FirePOWER.
This command doesnt work.
See the documentation:
Found it! ^_^
Worse case, you have to re-image it again
I have verified this command works, and resets the SFR module admin password back to Admin123
session sfr do password-reset
SFR version 6.1.0
ASA version 18.104.22.168
Confirm for: Cisco ASA 5525
Login into ASA CLI, enter: session sfr do password-reset
next: session sfr console
Login in with admin/Admin123
In sfr console enter: configure
Change password to a new one.
