Hi Team Go!
I wrote a tutorial to help those who need to quickly secure their Go APIs and easily enable passwordless authentication using magic links without needing to manage a full-fledged authentication and authorization system: https://dev.to/magiclabs/securing-a-go-backed-scrappy-twitter-api-with-magic-3o01
I hope it helps!
Also, feel free to reach out if you ever need help with authentication, authorization or user identity @seemcat.
