24 alternatives to 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…

   Hi HN! I built KeyPub.sh to solve the problem of user verification for CLI applications. It's essentially OAuth for the terminal, but using SSH keys that developers and users already have. - No installation needed - works with existing SSH setup - Privacy-focused: users control what email info is shared - Simple email verification process - Free public service - Perfect for CLI app developers who don't want to build user verification Try it with: `$ ssh keypub.sh about` Source code: https://github.com/skariel/keypub
