Login without a Password
WARNING: Allowing Login without a Password
Using the passwordless login feature on any system that can be physically ac-
cessed by more than one person is a potential security risk. Any user accessing
this system can manipulate the data on it. If your system contains confidential
data, do not use this functionality.
Login without a password automatically logs a user into the system after the user enters
the username in the login manager. It is available to multiple users on a system and
works only with KDM or GDM.
To activate the function, select the user from the list of users and click Expert Options
> Login Settings. Then choose Passwordless Login and click OK.
To deactivate this function, select the user for whom to disable this functionality from
the list of users and click Expert Options > Login Settings. Then uncheck Passwordless
Login and click OK.
Disabling User Login

identity several system-related tasks should be managed, disable the user login when
creating the user account. Proceed as follows:
1 Click Add.
2 Enter the required data for User Data.
3 Check Disable User Login.
4 Apply your settings with Accept.
To disable login for an existing user, proceed as follows:
