Keychain
Keychain in Mac OS X / macOS password manager that safely stores and encrypts saved information like account information, banking information, and other sensitive material. In the event that a user forgets the password to access their Keychain, there is a simple way to reset that Keychain password in macOS.
Procedure
- In macOS, open the Finder.
- With Finder open, press "Go" in the top-left of the screen, and then select "Utilities" from the drop-down menu.
- In the Utilities folder, open "Keychain Access".
- With Keychain Access open, select "Keychain Access" in the top-left of your screen, and then select "Preferences" from the drop-down menu.
- In the Preferences menu, press "Reset Default Keychains..." and sign in with the account password (if it is a university device, use your Southeast account password).
- When prompted, enter the password a second time; this is a normal, extra layer of security for macOS.
- A message should appear that says "Created a new empty "login" keychain with no password. Please change password using Edit > Change Password for Keychain." Press "OK".
This will create a new, empty Keychain that will store future login information in a safe, encrypted manner.
