You touch a door, window, gate, chest, or other entryway that is closed, and it becomes locked for the duration of the spell. You and the creatures you designate when you cast this spell can open the object normally. You can also set a password that, when spoken within 5 feet of the object, suppresses this spell for 1 minute. Otherwise, the object stays locked until it’s broken or the spell is dispelled or suppressed. Casting knock on the object suppresses arcane lock for 10 minutes.

While affected by this spell, the object is more difficult to break or pick; the DC to break it or pick any lock on it increases by 10.
