At polar55, you have the option to set up 2-factor authentication for your account.
All you need to do is activate it under Edit my account -> My Account -> Security settings.
Afterward, you need to configure your two-factor authentication app with your Polar55 login. The next time you log in with us, your login will require two-factor authentication.
If you lose access to your authenticator app, our support team can always disable two-factor authentication on your account. This way, you can log in using your email and password instead.
