Logging into a Mac after password change


I just changed my network username and now I get "system was unable to unlock your login keychain".
When opening a program I am receiving a pop up asking for the keychain password. example: "Adobe Acrobat wants to use the "Local Items" keychain."

Best practice for MacOS users would be to update their passwords on a different device through the MyGRCC Portal to prevent issues.

After changing the campus network password, users will be prompted with the message: The system was unable to unlock your login keychain.

Always choose Create New Keychain

Choosing Continue to Login will cause a mismatch in keychains. The only way to fix this issue is for the user to change their password on a difference device and chose Create New Keychain upon next login.
