Sign in to yahoo using gmail

Unfortunately, it's not possible to sign in to Yahoo using a Gmail account. Yahoo and Gmail are two separate email services that use different authentication systems.

Yahoo uses its own login system, which requires a Yahoo account and password. If you don't have a Yahoo account, you can create one by signing up on the Yahoo website.

Gmail, on the other hand, is a service provided by Google, and it uses Google's own login system. You can sign in to Gmail using your Google account credentials, but you can't use a Gmail account to sign in to Yahoo.

If you're trying to access a Yahoo service or feature that requires a login, you'll need to create a Yahoo account or use an existing one. If you're having trouble signing in to Yahoo, you can try resetting your password or contacting Yahoo's customer support for assistance.
