2FA Enrollment

ExchangeDefender supports multi-factor authentication (MFA) and two-factor (2FA) to further secure your accounts.

After you login at click on Settings > Multifactor Auth (2FA OTP) and scan the QR code using the MFA authenticator app of your choice. Type in the code and you'll see the enrollment confirmation:
