What is account key in yahoo mail

In Yahoo Mail, an Account Key is a security feature that provides an additional layer of protection to your account. It's a unique, 16-character code that you can use to sign in to your Yahoo account instead of your password.

Here's how it works:

1. You enable Account Key in your Yahoo Mail settings.
2. When you try to sign in to your account, you'll be prompted to enter your Account Key instead of your password.
3. You'll receive a notification on your device (e.g., your phone or tablet) with a 6-digit code.
4. Enter the code on the Yahoo sign-in page to complete the login process.

The Account Key is tied to your device, so you'll need to have your device with you to sign in to your Yahoo account. This adds an extra layer of security, as even if someone knows your password, they won't be able to sign in without your device.

To enable Account Key in Yahoo Mail:

1. Sign in to your Yahoo Mail account.
2. Click on your profile picture or avatar in the top right corner.
3. Select "Settings" from the dropdown menu.
4. Scroll down to the "Account" section.
5. Click on "Account Key" and toggle the switch to "On".
6. Follow the prompts to set up your Account Key.

Note that you can always switch back to using your password to sign in if you prefer.
