Of the ways listed, which is the best way to temporarily suspend a user's ability to interactively login?

Changing a user's UID (User ID) would severely impact file ownership and permissions, potentially making their files inaccessible and causing system inconsistencies.

Changing the user's password would prevent them from logging in with their old password, but they could still log in if they learned the new one or if an admin provided it.

Changing a user's login shell to `/bin/false` (or `/sbin/nologin`) prevents them from establishing an interactive session, as these programs immediately exit upon execution. This approach maintains the user's account, files, and permissions, allowing for easy restoration of login access by changing the shell back.

Removing the user's entry in `/etc/passwd` would effectively delete the user account, which is a permanent and highly destructive action, not a temporary suspension.

Placing `logout` in the user's profile file (e.g., `~/.bash_profile`) would log them out immediately after login, but they might still briefly get a shell or cause issues with non-interactive processes.
