Got me Pebble Time yesterday! Yay. Found a cool app for Two-Factor Authentication codes called QuickAuth (it’s open source too, amazing!).
The app requires you to enter the secret keys for your Two-Factor Authentication sites. Unfortunately I never saved these when I set up TFA on my devices. I was smart enough to save the QR code for each site and this way I was always able to add new devices by just scanning the saved QR code, but now I had to enter the secret key and I was stuck.
Enter another open source project Zebra Crossing (zxing). This is a library for processing QR codes and they have an Android app called Barcode Scanner. Get this app, scan the QR code, and you get an output that starts with
otp://. That’s the secret key you want. Enter this into QuickAuth.
If you don’t want to download the app there’s also an online interface to upload a QR code and decode. Nice!
p.s. In case it helps anyone – on the face of it there seems to be no easy way to delete a key/ site once you enter it into QuickAuth. Later I realized if I long press the select button on the pebble when it shows a code I get many options. One of these lets you delete the key/ site.
