Yahoo! has introduced a new stroner user authentication fetures to the users residing in the United States, Canada, India, and the Philippines.
The new authentication feature aims to prevent account hijackers with a stolen password from accessing a person's account. "If you have a Yahoo! account, you can now further protect it by activating this new second sign-in verification feature from Yahoo! Account Info. As part of the process, you will be required to add a mobile phone number to your account and verify it via SMS," informs Yahoo.
"Once the feature is turned on, any suspicious account sign-in attempt will be challenged by a second sign-in verification beyond the initial password validation. To confirm the legitimacy of the sign-in attempt, you or the hijacker will have to answer your account security question or enter a verification code that will be sent to your mobile phone. Presumably, only you, as the legitimate user, can sign in. Account hijackers will be blocked since they neither know your security answer nor possess your mobile phone," explains Yahoo.
In short, this "second sign-in verification step acts as an additional, stronger 'beyond-the-password' challenge against any unauthorized access attempt. And our systems are also capable of other refinements to accomplish our ultimate goal: to block all account hijackers from accessing Yahoo! accounts," Yahoo said.
Yahoo! promises to bring this feature to all worldwide users by March 2012.
