OS X Mountain Lion: About your keychain password
Your keychain password lets you automatically authenticate apps and services stored in Keychain Access. When a user is created, the keychain password is set to match the login password for the user.
When you change the login password in the Users & Groups preferences, the keychain password is automatically updated to match it.
If the keychain password does not match your login password for the you must also enter a password to unlock the keychain.
The keychain password is available only to the user and not the administrator. If the login password is reset by the administrator, the keychain password is not changed. The user is asked to reset the keychain password during the next login. If the login password was reset because the user forgot the old password, the keys, passwords, and other information in the keychain will not be accessible, and the user will need to create a new keychain.
Although you normally should use the default keychain password, you can change it.
- Open Keychain Access, located in the Utilities folder.
- Choose Edit > “Change Password for Keychain [keychain name].”
- If the keychain is locked, type the password to unlock it, and then click OK.
- Type the current password for this keychain.
- Type a new password, and then type it again to verify.
The keychain password usually matches the user’s login password.
- Click OK.
