Vlock is a Linux program that enables users to lock one or multiple sessions on the console. It is designed to enhance user privacy and security by preventing unauthorized access to the system.
Additionally, if you want to lock the entire console and disable virtual console switching, that's possible too. However, to use vlock, you'll need Linux-PAM version 0.76 or higher.
In terms of recent updates, the latest release includes some slight changes to the build system to make it easier for distributors. It also now displays the number of failed authentication tries on exit. Overall, if you need to lock Linux console sessions, give vlock a try!
