There's nothing worse than being in a hurry and not remembering your password. Fortunately, with Mac OS X’s built-in password manager, you can easily recover those lost passwords without having to bother with the password reset debacle. Use Keychain Access to search for and retrieve any saved password.
To get started, open the Keychain Access app (located in /Applications/Utilities). This is the built-in password manager for Mac OS X. When you save passwords in applications like Mail and Safari, this is where you can access them.
Under the Keychains section on the left-hand side of the app, select login. You should now see a list of websites and applications that use Keychain Access to store login information. Scroll down through this list until you get to the login item that you’ve forgotten. When you find it, double-click it (or single-click and select the “i” button at the bottom of the screen).
