Generating Authy passwords on other authenticators

---

*update: This might affect how easy it is to use this technique past August 2024: https://www.theverge.com/2024/1/8/24030477/authy-desktop-app-shutting-down

---

There is an increasing count of applications which use Authy for two-factor authentication. However many users who aren't using Authy, have their own authenticator setup up already and do not wish to use two applications for generating passwords.

Since I use 1Password for all of my password storing/generating needs, I was looking for a solution to use Authy passwords on that. I couldn't find any completely working solutions, however I stumbled upon a gist by Brian Hartvigsen. His post had a neat code with it to generate QR codes for you to use on your favorite authenticator.

# 1) install a standard ubuntu server from the server image
# 2) during server installation you will have to create a user, so create a throwaway user, ie 'tmpinstall'
# 3) login to that throwaway user 'tmpinstall' after the server is up
# 4) install any additional packages and even any special users that you want to always
#    be there in your base image template
# 5) when finished, become a clean root shell for the next steps:
