4.10.4 Language
In this menu you can change the Webmin interface language. The default language is English.
4.10.5 Authentication
Here you can set the authentication and password timeouts. Password timeouts can protect against
socalled brute force attacks, because they initiate an increasingly delayed logon procedure after an
abortive logon attempt has taken place. When the authentication is activated, the sessions of all users are
logged by the Webmin, all inactive users will be automatically logged off.
Note
Activation or deactivation of the authentication can result in all users needing to log in again.
