Hi there Bill. My name is*****'d be happy to help you with this. It sounds like perhaps Verizon changed your original password ***** Yahoo. I can help you fix this is if you'll provide a little more information. What type of phone do you have? What is the other app (besides the Yahoo mail app) that you use for email. Also, do you know what your current Yahoo password?
You are very welcome. Have a great day!
