A closed entryway you are touching is now locked magically. The door (or window, gate, chest, etc.) will be extra difficult to break or pick the lock of (add 10 to the DC for either) unless the spell is dispelled or suppressed.

You can designate who, in addition to yourself, can open the door normally, and you can set a password that will suppress the spell for 1 minute if spoken within 5 feet of the door. Anyone who casts knock on the door will also suppress the spell for 10 minutes.
