All of a sudden I get an error with my email stating invalid password both on my phone and iPad. Nothing changed. It worked last night and today nothing. I can access my AOL mail through my desktop. It’s really frustrating!!!

AOL/Yahoo/BellSouth/AT&T (which are now all the same provider) changed the way they authenticate email. Here is a thread that discusses the problem and the solution→bellsouth.net email not working iOS 14.4.1 - Apple Community

AOL changed the password requirements a while ago. This thread discusses how to fix it→AOL mail error - Apple Community
