Yahoo 2-Step Verification


Two-step verification (2SV), or two-factor authentication (2FA), is a powerful security measure that adds an extra layer of protection to online accounts. By requiring users to provide two different authentication factors, such as a password and a unique code or physical device, 2FA significantly reduces the risk of unauthorized access and enhances account security.

Implementing two-step verification is relatively easy and widely supported by popular online services, including email providers, social media platforms, and financial institutions. Even if an attacker manages to obtain a user’s password through various means, they would still need physical access to the second factor or knowledge of the unique temporary code to gain entry. This adds a crucial layer of protection that significantly reduces the chances of successful account breaches.

Yahoo! 2-step verification

Go to your Yahoo Account Security page and click on Turn on 2SV.

Select your preferred 2SV method. For this guide, we’ll select the phone number.

For security purposes, you may be asked to enter your password again.

Select the phone number to be used for 2SV. You may choose the number that you currently use for the Yahoo account or you may use a different one.

Enter the verification code sent via SMS and click Continue.

You’ll get routed back to the Account Security page but this time, you’ll see that the 2SV is enabled for the account.

Whenever you sign in using your Yahoo! credentials to another app, or even to the Yahoo! website, you will be sent an additional security code via SMS or email to confirm that it’s indeed you who’s trying to access the account.


By requiring two different factors for authentication, two-step verification significantly enhances the security of online accounts. It mitigates the risks associated with weak or compromised passwords and protects against automated attacks, phishing attempts, and unauthorized access attempts.
