Mail Repeatedly Requesting Password

I've browsed several topics similar, but none have been exactly the same as my problem and none have solved it. Up until last night, my mail was working fine. I'm in college, so I tend to just leave it open whenever I'm at my computer. All of a sudden it started asking for my password over and over and over. I know what I'm entering is right. I've done all the things Help has suggested to do. I thought it was just my network, but then I still couldn't access my mail from mail2web.com. I'm expecting a few really important messages. How can I fix it?

Sounds like your email provider's servers are having problems. May want to contact them or wait it out.

A Solution?

I experienced this problem before as well. I believe it occurred because I neglected my gmail account for a really long time. In any case, I solved the problem by simply ticking the "Stay signed in" option at the log in page (below the password input box).

Try it out and let me know if it works for you as well.

Good luck.

This is a fairly common problem. It is surprisingly common with users who
have Comcast as their ISP. It is due to a timing issue between Mail
and certain ISP's. Mail gives your account password before your ISP's
server is ready for it. When the server is finally ready for it, the
password has already been given, and the server must request it again.

There is a potential work-around for the problem here:
Apple - Support - Discussions - random password request in mail ...

"...[go] into the Keychain application, located in the Utilities
folder. In the upper left column, highlight "log-in." In the lower
left column, highlight "passwords." In the right window scroll until
you find your "mail.comcast.net and smtp.comcast.net" or whatever your
internet service provider incoming/outgoing mail servers are called.
Double click on each which will bring up an attributes/access control
window. Select access control. Then select the bullet next to "allow
all applications to access this item." Make sure you do this for both
the incoming server (mail.comcast.net) and outgoing server
(smtp.comcast.net) keychain items. "
