sudo may be configured to stop requesting passwords for specific commands to specific users or groups. This is very convenient for personal computers where there is only a user (and therefore she’s the administrator).
With next file /etc/sudoers, the sudo group members will be allowed to run apt, apt-get and dpkg commands absolutelly with no password.
For other users, the sudo behaviour do not change.

Cmnd_Alias APT = /usr/bin/apt, /usr/bin/apt-get, /usr/bin/dpkg
%sudo ALL = ALL, NOPASSWD: APT
Option ‘timestamp_timeout’ sets the time (in minutes) that the password will remain in cache, so it will not ask for it during that period. The value 0 disables the cache.
