I’ve enabled the FB Code Generator (one-time passwords for secure login on new devices). I’ve already got 5 other accounts set up in Google Authenticator, so it’d be great if I could export my FB otp key for use in that app.
Between simulators, browsers, and test devices, I actually have to use this pretty often. It’s kinda annoying that I have to start the FB app, tap the menu, scroll to the bottom of the huge list, and tap code generator (at least 5 seconds from a cold start)… When I can pull up the Google Authenticator app in approximately half a second.
Barring the ability to export keys, is there at least some way I can set my TOTP key via the API or something?
Yes. Facebook uses the standard TOTP algorithm and will need to accommodate the use case where you didn’t have mobile internet access (hence key/seed fetching unavailable).
Look for the “having trouble?” link in the popped up dialog in your browser when setting up code generator, it will lead you to a seed/key. Just feed that into your Google Authenticator and verify the first code, it should work 🙂
