My iPhone suddenly want accept my e-mail password?

The message says "Can't get mail. The user name or password is incorrect. I've checked to make sure both are correct. (They are) and I have no problem getting into e-mail from my laptop or browser with the same password. Yesterday it was fine. What can I do?

What you have to do is go into your mail and correct your password. If that doesn't work then you have to go to your email and change your password. That's the only way it will work

Try going to settings, then remove your email account from your phone, then putting it back on

I have the same problem with my itouch.lol
