Troubleshooting keychain issues

Is Safari no longer remembering logins and passwords? Is asking for a password every time you launch the app and try to check or send mail, despite the fact that you’ve entered login credentials over and over? When a Mac app no longer remembers password and login data, it’s often the result of corrupted keychain files. This is easy to fix in three easy steps with Keychain Access first aid.

• Launch Keychain Access located in /Applications/Utilities
• Open the "Keychain Access" menu and choose "Keychain First Aid"
• Enter the user’s password and check the "Repair" box, then click "Start"

After keychain repairs are completed, exit out of Keychain Access and return to the application that wasn't remembering the login and password information. You may be asked one more time for the login, but from this point on it should remember it.
