Open2FA – a CLI 2FA tool with optional secure remote capabilities
This is a tool I started working on whenever pypi decided to make 2FA mandatory. I've already been using it to login to pypi for a while, but only finished the remote capabilities recently. It can be installed by simply running: `pip install open2fa` Any secrets that are stored remotely are encrypted, so the person running the api (me) provably cannot use any remotely stored secrets. It's possible to use pushed TOTP secrets from any device with the open2fa CLI installed, as long as the original UUID is known. It's also possible to use any pushed secrets to generate 2FA codes from any device…
