Authy without snap

Authy is a two factor authenticator that synchronises between different machines. On linus you can only install is when you install snap on your system. Debian11 does not ship with snap. You can however run Authy without snap though I don't really recommend this, but if you have no other alternative:

sudo apt Install npm

Install electron 9.0.0 (Later version of electron 9 may work, but this version does work):

npm i -D electron@9.0.0

Download Authy Windows installer from website. https://authy.com/download/

Extract authy-X.X.X-full.nupkg file from the downloaded exe file using nemo or nautilus file extractor.

Extract lib/net45/resources/app.asar from .nupkg file using nemo or nautilus file extractor.

Run

~/node_modules/.bin/electron /<where you saved it>/app.asar

to launch Authy.

e.g.:

~/node_modules/.bin/electron /home/yourname/Downloads/app.asar

now make a textfile and enter this line. Save it on the desktop with authy.sh as name and make it executable.

Authy should work now!
