A lot of times, Hotmail uses part of your name, as the username for the account. Lately though, I have noticed that Hotmail is also available through Outlook email.The best possibility is to think back to when you opened the account, and see if you can figure out the information you used back then. Also, you can go to Hotmail, and click on the u201cForgot Username,u201d or the u201cForgot Password,u201d prompts which will help you discover those that you used for setting up your account.Iu2019ve had mine since 1995, and, fortunately, my username is easy to remember, and the password is the same as my Windows lock screen, and that helps me to remember.
