Ratings and reviews

IT GETS THE JOB DONE. Supports authentication-lock via fingerprint/PIN, has pretty logos OOTB for most websites, and even supports Steam's kooky alt-TOTP algorithm. The only reservation I have is that it didn't seem to work as a URI handler (e.g. when a QR code is scanned from the native Camera app) on my phone; but I could still scan them from *within* the app; and, seeing the developers' work on other issues it's had, I'm sure this will be fixed shortly. This is clearly *the* TOTP/HOTP app.

Sadly, while this worked with my old kitkat device, it no longer is able to *scan* the code in with my new pie device. While not a big deal, since there are alternative methods of input, it was a nice convenience. I never saw anything stand out in the logcat. I also have the app "Barcode Scanner" installed, and it had no problem scanning the code in. I also just installed andOTP, and so far it's working right. It looks to use the same scanning interface as the Barcode Scanner.

Found this when looking for open source 2FA with backup & restore capability. Export to and import from JSON works. 2 major bugs though: 1) QR scanner never scans (weird, since it works in FreeOTP). 2) Can't edit or delete entries: once created, an entry is immutable and permanent (weird, since FreeOTP can do this). Otherwise, this app is exactly what I'm seeking!
