The most important questions:

Is my email content secure?

Yes, INVISID does not read the email content. It only processes the keystrokes and saves them in a processed form. Attackers can therefore not deduce or imitate the typing pattern.

How is my behavior learned and what happens if I type differently?

INVISID learns your typing behavior when you register. You can also easily add more emails as training data in your dashboard. This allows you to retrain INVISID in any situation. If necessary, you can (currently) "overwrite" your typing pattern with a 2FA token via an Authentificator app

The recipient does not use INVISID. Does it still work?

Yes, INVISID certificates can also be checked manually at invisid.de/certificates . All you need is the .eml file of the received message. You can simply download this in the e-mail client.

Which email providers does INVISID work with

INVISID currently supports Gmail and Outlook in Chrome and Edge, as well as the new Outlook for Desktop. Other providers and browsers will follow.

Can I still use INVISID if I injure myself?

Of course! Since INVISID follows an AI-based approach, it continuously learns from your behavior and keeps refining your typing pattern. If your style changes drastically due to an injury, INVISID offers fall-back security measures in order to verify your identity and consequently adapts to your new style.
