What is an account key in yahoo mail

In Yahoo Mail, an account key is a unique code that is used to verify your identity when you sign in to your account from a new device or browser. It's an additional security measure to prevent unauthorized access to your account.

When you sign in to your Yahoo Mail account from a new device or browser, you may be prompted to enter an account key. This key is sent to your registered mobile phone number or alternative email address, and you need to enter it to complete the sign-in process.

Here's how account keys work:

  1. When you sign in to your Yahoo Mail account from a new device or browser, you may be prompted to enter an account key.
  2. Yahoo sends a one-time code to your registered mobile phone number or alternative email address.
  3. You enter the code to complete the sign-in process.

Account keys are used to verify your identity and ensure that you're the actual owner of the account. They're an additional layer of security to prevent unauthorized access to your account, even if someone knows your login credentials.

You can manage your account keys in your Yahoo Mail settings. Here's how:

  1. Sign in to your Yahoo Mail account.
  2. Click on your profile picture or avatar in the top right corner of the page.
  3. Click on "Settings" from the dropdown menu.
  4. Scroll down to the "Account" section.
  5. Click on "Account security" or "Two-step verification".
  6. Look for the "Account key" or "One-time code" option and toggle it on or off.

Note that account keys are different from two-factor authentication (2FA) codes, which are used to verify your identity in addition to your password. Account keys are specifically used to verify your identity when signing in from a new device or browser.
