It is multi-tenency- and multi-instance-capable. Due to the modular structure privacyIDEA can be quickly and easily adapted and enhanced. E.g. adding new token types is as simple as writing a new lean python module. You do not need to modify your network for privacyIDEA, it does not write to existing databases or user stores. It only needs read access to your user stores like LDAP, Active Directory, SQL, SCIM-service or flat files. Existing workflows can be enhanced without the need to modify them. Using its simple REST like API it can be automated and smoothly be integrated. The Smartphone App "privacyIDEA Authenticator" turns your smartphone into an authentication device, which smoothlessly runs with the privacyIDEA backend. In contrast to classical smartphone based tokens the privacyIDEA Authenticator also allows for a more secure rollout process. ## Key features - Two-factor authentication - OTP token support - Secure rollout process - Smartphone as authentication device - REST API integration ## Recent user reviews (10 of 14) All indexed reviews: https://appshunter.io/ios/app/privacyidea-authenticator/id1445401301/reviews.md ### 1/5 — Telefoniert nach Hause bei jedem Login *2026-06-15* Was da wohl übermittelt wird…. ### 1/5 — Telefoniert nach Hause bei jedem Login *2026-04-25* Was da wohl übermittelt wird…. ### 3/5 — Missing Apple Watch integration *2025-03-15* The app works well, but I would like to receive PUSH requests directly on my Apple Watch. It would be enough to approve PUSH tokens direct from the notification, with no need to develop a separate Apple Watch app. If you add this feature, I promise I’ll improve my rating! ### 1/5 — 👎 *2024-12-07, version 4.4.0* Бесполезное и ужасное приложение ### 5/5 — Desaster (beseitigt) *2024-07-19* Seit heute stürzt die App sofort nach dem Start ab. Dies war seit dem vorletzten Update immer nur beim Code wechsel der Fall. Da mit dieser App alle Privaten und Unternehmenszugänge gespeichert wurden ist eine Anmeldung an keinem System mehr möglich. Da es auch keine Export Möglichkeit gibt (wollte schon zur Sicherheit seit den letzten Abstürzen ein Backup erstellen) sind nun alle Zugänge verloren. Vielleicht liest der Hersteller ja mit, da wir eine lizenzierte Version betreiben, ist das Desaster um so größer, da wir auf eine funktionierende Anwendung für unsere Kunden angewiesen sind. Nur diese Software bietet den Push Token! An dieser Stelle möchte ich auch nochmal auf die fehlende Sicherung der Token dur TouchID oder FaceID hinweisen. Der Absturz wurde zeitnah behoben und alle Token stehen wieder zur Verfügung, DANKE und 4 Sterne. Vielleicht kommt die Absicherung per Touch-/FaceID ja auch in die Anwendung. Dann gibt es 5 Sterne. Die Absicherung steht, wie ich erfahren habe, schon länger zur Verfügung und funktioniert pro Token und nicht global. **Developer response:** Vielen Dank für die Treue und das Update. FaceID/TouchID geht schon lange. Hier ist zu beachten, dass wir den Schutz per FaceID pro Token einstellen. Das liegt daran, dass wir mit dem privacyIDEA-Server auch diesen Schutz erzwingen können. Wenn Du eine eigenen Token in der App mit FaceID schützen möchtest, dann kannst Du nach links swipen und dann "Sperren" auswählen. In Zukunft siehst Du den Code nur, wenn das richtige Gesicht vor dem Handy sitzt. ### 3/5 — Backup possibility and Apple Watch extension *2024-06-20* Would appreciate an easy backup possibility (e.g. iCloud) and an Apple Watch extension for push authentication… ### 2/5 — Kein Split View Support mehr auf iPadOS *2023-12-19* Warum wurde das entfernt? Die App ist jetzt einfach unnötig groß; auch im Stage Manager. ### 1/5 — Pui *2023-12-18, version 4.2.3* Ушлёпки тупоголовые зачем вы обновили приложение, оно теперь не работает на старых прошивках! СРОЧНО СДЕЛАЙТЕ ДАУНГРЕЙТ ### 4/5 — Push Benachrichtigung funktioniert nicht mehr *2022-06-17* Seit der Version 4.0.0 wird eine Auth-Anfrage nicht mehr per Push mitgeteilt, man muss manuell die App öffnen und selbst aktualisieren. Since version 4.0.0 auth-requests are no longer pushed. You have to manually open the app and actualize to see the request. ### 4/5 — Version für Apple Watch fehlt! *2022-05-07* Die App ist gut. Ich bin von OTP umgestiegen und dort gab es eine Version für die Apple Watch, war sehr gut und hilfreich ist. ## Frequently asked questions about privacyIDEA Authenticator ### What is privacyIDEA Authenticator? privacyIDEA Authenticator turns your smartphone into an authentication device for two-factor authentication.
