How to know the yahoo mail in facebook

I think there may be a bit of confusion here!

Yahoo Mail is a separate email service from Facebook, and it's not possible to directly link a Yahoo Mail account to a Facebook account. However, I can provide some possible ways to access your Yahoo Mail account from Facebook:

  1. Facebook's built-in email feature: Facebook allows you to add an external email account, including Yahoo Mail, to your Facebook profile. To do this:
    • Go to your Facebook profile settings (click on the downward arrow in the top right corner).
    • Click on "Settings" and then "Account Settings".
    • Scroll down to the "Email" section and click on "Add account".
    • Enter your Yahoo Mail email address and password to link it to your Facebook account.
  2. Yahoo Mail app on Facebook: Facebook has a built-in app for Yahoo Mail, which allows you to access your Yahoo Mail account directly from Facebook. To find it:
    • Go to your Facebook homepage and click on the "Apps" icon (looks like a grid of squares).
    • Search for "Yahoo Mail" and click on the app to open it.
    • Sign in with your Yahoo Mail credentials to access your account.
  3. Third-party email clients: You can also use third-party email clients, such as Microsoft Outlook or Mozilla Thunderbird, to access your Yahoo Mail account. These clients often have integrations with Facebook, allowing you to access your Yahoo Mail account from within the client.

Please note that linking your Yahoo Mail account to Facebook may allow Facebook to access your Yahoo Mail data, so be sure to review the terms and conditions before linking the accounts.
