Description

From the listing uploaded by “appupdater”.

The Airlock 2FA app offers simple and secure two-factor authentication and transaction approval using your Android device. It can only be used with websites integrated with the Airlock IAM solution. Login credentials from the website or an activation letter from the service provider (e.g. your bank or insurance) are required to use the app. The features available in the app may be restricted by the service provider. In case of problems, it is therefore recommended to contact the customer support of the service provider directly. Airlock 2FA app provides the following features: - Login with One-Touch (using push notifications) - Login with QR codes - Login with Passcode (time-based one-time codes) - Transaction approval with One-Touch (using push notifications) - Transaction approval with QR codes - Activation using QR codes - Recovery from smartphone backup (if enabled by the service provider) Recorded audio data never leaves the smartphone and is not stored permanently (see also chapter 11 of the privacy policy). You can also deny access to the microphone and still use the app.
