Your Yahoo account is always protected by a password. As an added precaution, the site asks that you select a security question and provide an answer unique to you. With any luck, your security questions are personal enough that you can easily remember the answers. Unfortunately,sometimes you may forget the answers to your security questions. It is still possible to access your account without knowing your password or the security questions.

Purpose of the Security Question

You do not need to use your security question each time you sign in to your Yahoo mail your password will suffice.

The security question feature is an extra security measure used to reset a lost password.

You must provide the correct answer to your security question, which you provided when you set up the question, if you have forgotten the password for your email account.

Accessing Your Account Without the Security Question

If you have forgotten your password and don't know the answer to your security question, there is an alternative way to get your password.

When you signed up for Yahoo, the site asked you to provide another email address.

If you forget the password to your Yahoo mail account, request that it be sent to your other email address.

Yahoo will send a link to that email that lets you reset your password and access Yahoo mail.

Resetting Your Security Questions

Once you regain access to your Yahoo mail account, it is important to change your security question to something you will remember in the future.

Click on your name, select the "Account Info" tab and re-enter your password.

Under Sign-In and Security, choose "Update password - reset info."

Choose your new security questions from the drop-down list proved and enter the appropriate answers. Click "Save" to set your new questions.

Considerations

When your email account has gone unused for quite awhile, Yahoo may put a hold on your account for 24 hours as a security measure.

If you still cannot remember your security questions after that time period, you are allowed to request a link to your alternate email address.

If you don't have an alternate email address, use the "Contact Yahoo!" link to send a message to customer service.

Without a password, alternate email address or security questions, a Yahoo representative must confirm your identity before you are allowed access to your account.
