AUTHADA

AUTHADA is a secure and user-friendly app designed to enable easy digital identity verification using official German identity documents such as the German ID card, residence permit, or EU eID card. By entering a 10-digit identification code from a service provider or scanning a QR code, users initiate the identification process. The app guides users step-by-step to enter their ID PIN, scan their NFC-enabled ID card, and provide a TAN to complete secure authentication.

The app ensures privacy and security at the highest level with certification from the German Federal Office for Information Security (BSI). No personal data is stored within the app or by AUTHADA, and all communication is encrypted. Additionally, AUTHADA supports features such as PIN reset and unlocking via a PUK code, with clear instructions for lost PIN situations. The app has been designed with accessibility in mind to accommodate as many users as possible.
