If you use Yahoo! as your Web mail provider, you're not alone. Created in 1997, Yahoo! Mail still ranks as the most popular e-mail provider in the United States, according to data from Experian Hitwise at the time of publication. Although much has changed since Yahoo! began providing e-mail, the simplicity of logging in has not.
Navigate to the Yahoo! Mail home page.
Click on the first text box, and enter your full Yahoo! ID. You don't need to include the "@yahoo.com" portion, but you can if you want.
Enter your password in the second text box. Your password is case-sensitive, so remember to capitalise it exactly as you did when you set up your account.
Click "Sign In" to log in to your Yahoo! Mail account.
