Interesting.
I have been researching how to dump the database of google authenticator (currently over 20 entries, some non recoverable), but the solution involves rooting my android phone and accessing a protected sqlite file, with a propietary (and version dependent) schema. I am not going to do that.
Does authy have the same workflow a google authenticator? Can I add entries with QR code? With ID? Can I dump the database in plaintext? (the IDs) Can it generate QRs for scanning with other 2fa tools?
Edit: ah, it's an online service. That kills it for me.
- CodeWriter23 9y ago1Password captures and stores TOTPs, even copies the current OTP into your clipboard momentarily when you log in to a site. You don’t have to use their online service; you can keep the password vault in a file. You can sync your devices over LAN and WiFi.

- gonvaled 9y agoCan you ellaborate?
- HappyRobot 9y agoYour passwords and two-factor keys should not be accessible through the same service. If 1Password is hacked, both forms of authentication are compromised.
- CodeWriter23 9y agoSo, if your phone using any password manager of your choice, Plus Google Authenticator for TOTPs is compromised, same level of risk, right? Because GA has no challenge nor authentication to dump your TOTPs.
- dexterdog 9y agoYes, but if you can put your 2fa manager behind something like samsung knox it gives you some level of separation.
- AdmiralAsshat 9y ago> Because GA has no challenge nor authentication to dump your TOTPs. Define "dump". GA won't challenge you to display the one-time TOTP code, no. It would be incumbent upon you to lock your device. But as far as dumping those codes out into a state such that a malicious actor could then take them and import them onto another device, no, that is not easily doable. As the distant parent noted, Google Authenticator stores the stuff in an encrypted sqlite database that is not extractable without root access. I don't think even run-of-the-mill adb debug commands can get it out.

- izacus 9y agoAuthenticator+ allows you to export it's data to file without going through rooting and whatnot.
- zaarn 9y agoI can recommend Authenticator+, it's a very nice and handy application. Though I've recently switched over to simply putting all the 2FA secrets in my keepass database, that's good enough for me in terms of security.
