[Harry Potter] Why didn’t Dumbledore make the entrance to the Third Floor Corridor immune to Alohomora?

It wasn't only a means of protecting the Philosopher's Stone, it was a deliberate *trap*. The idea is that anyone who would want to steal the Stone would be able to get through most, if not all of the traps bar the Mirror.

Dumbledore knew Voldemort was after it and designed it to play to his ego.
