Migrating one-time passwords from Authy to Raivo OTP

Migrating all of your OTPs from Authy to Raivo OTP.

[Note] This blog post is part of a series of migration guides that enable you migrate your OTPs from various OTP apps to Raivo OTP.


Authy has an extension for Chrome that allows you to view your OTPs in your browser. This extension will enable you to extract the tokens and generate QR-codes, which Raivo OTP can scan. The following guide is based on a GitHub Gist (link) from the user gboudreau, which a colleague of mine found online.

Migrating

  1. Install Authy from the Chrome Web Store (link).
  2. Open the Authy extension and sign in (make sure that the OTPs are visible by clicking on one of them)
  3. Go to the extensions page in Chrome (chrome://extensions/ or Menu > More tools > Extensions)
  4. Enable developer mode in the top right corner
  5. Click on the Authy extension and open the main.html file
  6. The Chrome developer console should now open.
  7. Paste the JavaScript (at the bottom of this page) into your console.
  8. You’ll now see QR-codes that you’ll be able to scan using Raivo OTP!
  9. When done, close the developer tools, disable developer mode, and uninstall the Authy extension.
