   Open2FA – a CLI 2FA tool with optional secure remote capabilities▲6

   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'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…
