What is an account key on 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 on your Yahoo account.
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 on your Yahoo account:

1. Sign in to your Yahoo account.
2. Click on your profile picture or avatar in the top right corner.
3. Select "Account info" from the dropdown menu.
4. Scroll down to the "Account security" section.
5. Click on "Account Key" and follow the prompts to enable it.

Note that you can use Account Key in addition to your password, not as a replacement. You can still use your password to sign in to your account if you prefer.
