    Keypub.sh – OAuth for the terminal using SSH keys▲222

    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
