I can't access Yahoo Mail on my Android because at sign in they ask me to fill in an old phone # which is defunct. I cannot find a manage account option to change the phone #-I'm new at this smart phone stuff. They don't give an option to sign in the old way. Thanks
If you can’t access Yahoo Mail due to an old phone number, try signing in on a computer and updating your recovery info under Account Settings. If you're locked out, go to Yahoo’s Account Recovery page and follow the steps to verify your identity. If that doesn’t work, Yahoo Support may be able to help.
Try opening Yahoo through a browser on your computer or mobile, go to your account settings, and change the old phone number through the "Security" or "Additional Settings" section. If that doesn't work, there's an option to recover access via email or other identity verification methods. They usually allow you to regain access without the old number if you can confirm your identity.
