Authentication vs. Authorization

Authentication verifies who a user is, confirming their identity using credentials like usernames and passwords. Authorization, on the other hand, determines what a user is allowed to access after they've been authenticated. In essence, authentication proves you are who you say you are, while authorization dictates what you can do.
