Verizon Email Sign-In Failed This is Error message is for a Verizon email account on a Samsung S5 phone. This afternoon it started saying the password changed and wants me to put the new password in, but I did NOT change my password. So I have no clue. This isn't the first time this has happened. I don't remember what fixed it the other times. Is it a Verizon issue or my account or my phone. So frustrating to keep hearing the notification over and over.
Have you tried to call Verizon? If not, it might help. Also try clicking forgot password. Sorry if this advice do not help. I'm only 14
