If you have Yahoo account and are using it to access your email, password, or other online accounts, you should take steps to protect yourself from being hacked. One way is to use a phone number or email address for your Yahoo account instead of your personal Yahoo username and password. This will help you if someone gets hold of your personal information like your name, address, or phone number. Another way to protect yourself is to use two-factor authentication (2FA). This means that you need to provide two pieces of evidence—a code that you generate and a physical piece of identification—to log in to your account. If someone gets hold of your 2FA code or physical identification, they can’t access your account.
