Comments on privacyIDEA Authenticator for Android

★★★★☆ Spoiala Ionut Remus · Jan 31, 2022

This app is great! It works with the privacyIDEA server and with other tokens used for 2FA login into various systems! One bug that I need to mention is that, if I accept a push and after the phones gets locked with the app running, the next push won't get passed through and if you unlock the screen of uour phone I see a blank white page with an undefined error only. To bypass this bug, I need to close the app before the screen lock, this way the next push gets through!

★★★★☆ Mrittunjoy Das · Feb 8, 2020

The push token auth "rollout url" doesn't work in android 9 and above. Please add following line in androidManifest.xml android:usesCleartextTraffic="true"

★★★★★ Joshua Nicoll · Sep 1, 2025

I had an issue with this app where my device UI was superimposed over the app UI, making it almost impossible to effectively use the app. However, after reporting the problem and app was updated within about 2 weeks to fix the issue. It's nice to see responsive delopers fixing issues quickly.

★☆☆☆☆ Gergely Németh · Sep 29, 2025

While the app seems nice, it's not able to copy or export tokens, as other authenticators could, that I used so far. It looks like, it was a big mistake to use this app, and now I have to make several requests to get my tokens working on a new phone.

★★☆☆☆ Mark Zamecsnik · May 15, 2020

Doesn't work on Pixel 3a with Android 10 because of toke store concerns. It says the phone is not supported.

★☆☆☆☆ J M · Oct 1, 2020

Just terrible. I keep getting error 905. Ok no drama. Contact support. Six months later issue is unresolved. I phone the support number get told they are in a meeting. Every single time I call the support staff are in a meeting. I email them. No reply. I am in shock this has gone on this long and this company does not care

Trust & Safety: The app requests a broad set of permissions (CAMERA, INTERNET, FOREGROUND_SERVICE, READ/WRITE_EXTERNAL_STORAGE, RECORD_AUDIO, USE_BIOMETRIC, USE_FINGERPRINT, VIBRATE, WAKE_LOCK, ACCESS_NETWORK_STATE, POST_NOTIFICATIONS) and includes a dynamic NOT_EXPORTED_PERMISSION. It reads from existing user stores via privacyIDEA backend and does not write to them, aligning with a security-focused OTP authenticator approach.
