Forgot an OS X Lion Password? Reset it Using an Apple ID
Aside from resetting a Mac OS X Lion password with the passwordreset command line tool or by creating a new user account, you can use a new feature in OS X 10.7 that allows a user password to be reset via the accompanying Apple ID, the same Apple ID that is tied to an iCloud, iTunes, App Store, and Apple Support account.
Resetting a Lost OS X Lion Password Using an Apple ID
Understand the caveats before beginning: this method only works if you set an Apple ID to tie with the OS X user account, and this option won’t be available for users with FileVault 2 protection enabled. Also note that this leads to the creation of a new keychain, but the old keychain will remain intact if you do recall the old password sometime down the road.
- After incorrectly entering a user password three times at the Mac login screen, a message appears saying “If you forgot your password, you can reset it using your Apple ID”, click the arrow button to bring up a “Reset Password” dialog
- Enter the Apple ID login information that is tied to the OS X Lion user account and click “Reset Password”
- Click “OK” to confirm the new keychain creation
- Enter and verify a new password, fill out the password hint field, and again click on “Reset Password”
- Click “Continue Log In” to login as the user account with the reset password
