Locks with keypads or biometric or whatever can be gotten in deadbolt and slip-latching door knob types. Deadbolt locks are generally considered higher security. For exterior doors, you generally want a deadbolt lock, but the slip-latching door knobs also typically installed can be gotten with or without locks.
With any lock, a reinforced strike plate and door frame can be used to increase resistance to kick-in attacks (some deadbolts come with reinforced strike plates). For installation of a strike plate in a typical door frame, the anchoring screws must be long enough to go into the framing stud, not the much weaker door frame.
