Quote from the vlock man page:

vlock works for console sessions primarily. However, there is support for trying to lock non-console sessions as well, but that support has not been well tested.

You can lock your terminal session using the vlock command.

$ vlock
This tty (pts/0) is not a virtual console.


The pts/0 is now locked by trainer.
Password:

The password is your user password.

It's there if you need it.
