i cant read any of my emails?

i have no problems. It may be possible that you need to update your web browser or switch to a different web browser. Internet Explorer has been having a lot of problems lately due to incompatibility issues with Yahoo. i highly recommend Chrome.

You can try switching to basic mail. Basic is similar to an early version of Yahoo Mail Classic. It's very simple design is easy to use but is lacking many advanced features only available on full featured Yahoo Mail.

On your Yahoo Mail page, hover over the gear icon in the upper right corner

Select Settings

Yes I cannot also read my emails from computer or iphone, I can log in but nothing is displaying tells me it cannot open the email, it then tells me I have registered for 2nd verification and need to do set up a password with my app sign in, not a computer or phone person so no clue how to do it

Same here, I have 2 accounts, one is working fine, this one I can't read my emails, they won't open up
