Two-Factor Authentication

How it works for the end-user

Install the Sound-Proof application
on your phone

Follow the online instructions to set up two-factor authentication for the website.

Login with username
and password

Keep your phone where it is - in your pocket, in a purse or on the table. Sound-Proof works as long as the phone is in the same room as your other device.

After three seconds ...

The phone and the PC automatically recorded ambient sound for a very short time. The recordings are compared by the phone. If the AI-enabled algorithm matches the recordings, you are logged in.
