:
sudoers uses time stamp files for credential caching. Once a user has
been authenticated, a time stamp is updated and the user may then use
sudo without a password for a short period of time (15 minutes unless
overridden by the timeout option. By default, sudoers uses a tty-based
time stamp which means that there is a separate time stamp for each of
a user's login sessions. The tty_tickets option can be disabled to
force the use of a single time stamp for all of a user's sessions.
[...]
tty_tickets If set, users must authenticate on a per-tty basis.
With this flag enabled, sudo will use a file named for
the tty the user is logged in on in the user's time
stamp directory. If disabled, the time stamp of the
directory is used instead. This flag is on by default.
