Help on signing in.
What does "Keep me signed in" mean?
If you check the "Keep me signed in" box, you can stay signed in to Yahoo on this computer for up to 2 weeks or until you sign out. To protect your personal information when you access some Yahoo services, we may ask you to enter your password again. The "Keep me signed in" checkbox applies to this computer only. If you're using a public computer, we recommend that you uncheck the checkbox. You can also modify the frequency by which you're asked for your password by clicking on My Account at the top of most Yahoo pages once you sign in. If you do so, Yahoo will ask you to verify your password more frequently, although your sign-in screen will still indicate every "two weeks". (More information on modifying your sign-in settings)
Concerned about password security?
Yahoo submits your ID and password using SSL, which provides a level of security when transmitting data. (More information on password security.)
What if I forgot my Yahoo ID or password?
We can send you your Yahoo ID or password after you confirm some personal information. Remember to use your full Yahoo ID (e.g. free2rhyme@yahoo.com) to sign in.
