Export TOTP tokens from Authy

Generating Authy passwords on other authenticators

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.

Istio on a local k3d cluster

Istio on a local k3d cluster

Sometimes it's more practical to have a local cluster for testing Istio stuff.


Install k3d. Tested on k3d 5.4.4, but it should work on the latest too:
