About two-factor authentication

Two-factor authentication (2FA) is an additional layer of security used when logging into a website or application. With 2FA, you must log in with your username and password and provide another form of authentication that only you know or can access.

For meross, the second form of authentication is a code generated by an application on your mobile device. After you enable 2FA, meross generates an authentication code any time someone attempts to sign into your account. The only way someone can sign into your account is if they know both your password and have access to the authentication code on your phone.

After you configure 2FA using a time-based one-time password (TOTP) mobile app, you can add a security key. We strongly urge you to enable 2FA for the safety of your account, not only on meross, but on other websites and apps that support 2FA.
