Unable to verify username and password for AOL Mail
El Capitan 10.11.6 I know this 24" Early 2009 iMac is an antique to most, but it serves my purpose with several apps that are no longer compatible with 64 bit OS on my MBP. I could find no solution to get Mac Mail working again with AOL - it had no problems until suddenly I got prompts to enter my password and couldn't. The usual solution to delete the account and add it back failed because it wouldn't accept my password and I got the same error message. I was unable to add the account back. I tried a new user account and booting in Safe Mode. Nothing worked. I spent many hours reading community boards, Apple Support documents and Mac web support sights - none worked. The solution is too simple to be true so I offer for those who need a fix:
Sign on to AOL Mail on the web.
Options>Account Information
Account Security>Manage app passwords
Select your app>Mac Mail
Generate - a new password specific to your OS will be generated
Use the new password to set up a new AOL account: System Preferences>Internet Accounts>AOL and follow the prompts entering the new password. The password is time limited so will not work later. The original password with your account will now work and you won't be prompted to enter you password . . . hopefully.
I hope this helps others!
