From the developer:
Chiff allows you to log in to any website using your phone, making logging safer and simpler. With Chiff's browser extension, you can securely connect your Chiff app to your browser by scanning a QR-code. Whenever you want to log in to a website, you receive a push message on your phone that you authorize with TouchID, FaceID or a passcode. Chiff sends your credentials to your browser and automatically logs you in.
