Reset a forgotten KeyChain Password
Hi everyone, My supervisor are using MacBook Air and had forgot the KeyChain Password. I'd tried to reset many time using Keychain Access console without success. can someone help me please?
It depends on which password he forgot.
Refer to If you need to update your keychain password on Mac
Excerpt:
Resetting the default keychain deletes all the passwords saved in the keychain, but should allow you to sync up your login password and the password stored in the keychain.
