By default, your FortiGate has an administrator account set up with the username
admin and no password. In order to prevent unauthorized access to the FortiGate, it is highly recommended that you add a password to this account.
In FortiOS 6.2.1 and later, adding a password to the admin administrator is mandatory. You will be prompted to configured it the first time you log in to the FortiGate using that account, after a factory reset, and after a new image installation.
- Go to System > Administrators.
- Edit the admin account.
- Click Change Password.
- If applicable, enter the current password in the Old Password field.
- Enter a password in the New Password field, then enter it again in the Confirm Password field.
- Click OK.
config system admin edit admin set password <password> next end
It is also recommended that you change the user name of this account; however, since you cannot change the user name of an account that is currently in use, a second administrator account must be created in order to do this.
