How to change Admin password on FXOS?

[zzkang12]

when I try to set new password of user admin, it said admin cannot reset self password.

How to set the new password of admin user?

firepower-fxos# scope security

firepower-fxos /security # show local-user User Name First Name Last name

admin

firepower-fxos /security # enter local-user admin

firepower-fxos /security/local-user # set password

Enter a password:

Confirm the password:

Software Error: Admin user admin cannot reset self password

If it is impossible to change but only can reset from the initialization then does it effect on the configuration of asa which is already set or the published license?

Here are the correct commands.  This assumes the ‘admin’ user.  It will require you to enter the old admin password as well as set the new admin password.
# scope security
# set password
# commit-buffer
