How do I reset my iCloud password.

Possibly I don't need to reset. The problem is I am getting a persistand message regarding Internet E-mail.

The following;

Server: p10-imap.mail.me.com

User Name:

Password:

I don't recall creating the user that is shown (would like to keep it private) name for any account regarding my email accounts.

It had a password entered that matches the number of characters I use in a secret password.

It offers me the chance to Save the passwor to my password list.

When I clicked OK the first time the input screen kept popping up....over and over again.

I then changed the password to another often used (thinking I may have set up this User Name/Password sequence)

The second 'guess' at the password produced no results and again the input screen keeps popping up.

Should I just close the iCloud account and start over, or just forget trying to match Apple application with my PC?

Thanks
