Scanning the QR code in a dedicated QR scanner app doesn't appear to work #10

@zeke tried to scan the code using a QR code scan app (Scan for iOS). It does open up Google Authenticator when you do that (but not Authy), but GA crashes. So you have to scan the thing directly into the auth app (Authy/GA) rahter than through a general scanner app.

We should either fix this, if possible, or at least document it.

Odd, @zeke was that for the terminal or browser qrcode?

zeke commented 10 years ago

@pedro both.

Scan.app redirects to Authenticator.app, which immediately crashes after I tap "Yes".

@zeke Can you still repro this?

This seems a lot more like a potential bug in the way that Scan.app and Authenticator are interacting. We know that Authenticator can properly interpret our QR codes, but seems to crash when entered through Scan.app. I'm going to close this out unless we can gather more proof that our codes are failing this process.

Maybe this was fixed when changing to correctly report issuer, instead of jamming it in with the email address?

brandur commented 10 years ago

Hah, maybe! Definitely worth another try.
