The User Editor window allows you to set user properties which are
User name
Set name of the new user.
User ID
Specify an ID for the user. This is normally not necessary, but
may be useful if you need to recreate the owner of an orphaned object. If
this is not specified, the highest assigned user ID plus one (with a minimum
of 100) will be used as default.
Password
Set user's password.
Note: If you do not plan to use password authentication you can omit this option, but then the user will not be able to connect if you decide to switch to password authentication.
Confirm Password
Re-type the password here.
Password Encryption

Set a date and time after which the user's password is no longer
valid. If this clause is omitted the password will be valid for all time.
