privacyIDEA Authenticator is a smartphone app that turns your device into an authentication device, providing a secure and convenient two-factor authentication solution. Developed by NetKnights GmbH, this app is designed to work smoothly with the privacyIDEA backend, a modular solution for two-factor authentication with OTP tokens.

The privacyIDEA Authenticator supports HOTP and TOTP authentication and also offers authentication via push notification, making it more secure than traditional smartphone-based tokens. The app provides a more secure rollout process, ensuring the safety of user data. With its simple REST-like API, privacyIDEA Authenticator can be smoothly integrated and automated, enhancing existing workflows without the need for modification. The privacyIDEA Authenticator is a multi-tenancy and multi-instance capable app, which can be easily adapted and enhanced by adding new token types through writing new lean Python modules. It requires only read access to user stores like LDAP, Active Directory, SQL, SCIM-service, or flat files, without any need to modify your network.
