   Extract one time password (OTP) secrets from QR codes exported by two-factor authentication (2FA) apps such as "Google Authenticator". The exported QR codes from authentication apps can be captured by camera, read from images, or read from text files. The secrets can be exported to JSON or CSV, or printed as QR codes to console.

   

   You can extract plaintext secret keys from google authenticator app and store them in user friendly format/password manager

   Discontinued :shit: Dealing with camera photos of QRCode exports

   The problem I had while my company phone got remote wiped: Google Authenticator uses a protobuf based export qr code, which any other 2FA app doesn't support.

   I wrote a small cli tool that can export all data inside it, and that tries to generate qrcode images for each entry for re-import into another 2fa app.

   I hope this can help someone with the same problem, I got stuck with a camera photo of this seemingly useless qrcose.

   Always remember to backup google authenticator, and always make a physical backup of your encrypted passwords database!

   OP: Do you still have adb running on the phone?

   If yes, then you might be able to backup google authenticator's data using adb.

   Maybe a tool like scrcpy [1] might be able to help when the screen is broken.
