Yahoo's online mail service allows you to access your e-mail to both read and send messages from any computer with Internet access. As long as you know your Yahoo ID and you account password, you can log in and read your messages in a few seconds.
Open your Web browser and navigate to the Yahoo Mail sign-in page (link in Resources).
Enter your Yahoo ID in the first box. This is the part of your e-mail address before the "@" sign.
Enter your Yahoo account password in the second box. Remember that passwords are case-sensitive.
Click the "Sign In" button to go to Yahoo Mail.
Click either the "Inbox" entry in the left pane, or the "Inbox" tab at the top of the page to view your Yahoo Mail inbox.
