You can configure sudo to require a password only every so many minutes. The default is 5 minutes. Read the sudoers man page and scroll down to this:

    timestamp_timeout
               Number of minutes that can elapse before sudo will ask
               for a passwd again.  The timeout may include a
               fractional component if minute granularity is
               insufficient, for example 2.5.  The default is 5.  Set
               this to 0 to always prompt for a password.  If set to a
               value less than 0 the user's timestamp will never
               expire.  This can be used to allow users to create or
               delete their own timestamps via sudo -v and sudo -k
               respectively.
