They Can Reset Your Passwords
If someone has the login credentials to your email address, chances are they’ll try to log into every platform they can. Since they have your email address, it’s possible to reset your passwords on other websites. What’s worse is that they could even change the password, or even the email address on other websites, making it impossible for you to log in, even if you manage to retrieve your email. They could even go one step farther and take control of your two-factor authentication security. That way, you wouldn’t be able to log in anymore even if you have the correct password or email.
