All of my Verizon email accounts have suddenly started giving me the message "Sign in failed". When I tap the message it tells me the server password has changed and to enter the new password. Started today sometime in the AM, eastern time. It's not a password issue since I can still log in via a web browser using the password that supposedly has changed. It would be nice if Verizon could send out some type of message to let their users know when they're going to start messing with security settings in a production environment.
