What is Two-Factor Authentication?
With two-factor authentication (2FA), you can increase the security of your IONOS account simply and effectively and protect it from misuse. Access is only possible after entering two different credentials. You can use an Authenticator App or the IONOS Mobile App for this purpose.
Easy to use
Using Two-Factor Authentication is very easy: Simply enter the 6-digit code generated by the Authenticator app while logging in to your IONOS account. If you are using the IONOS mobile app, you only need to confirm a yes/no dialog.
