Anyone remember Auth0 and passportjs?

The churn of auth services is never ending, but I suppose so are the standards.

Disclaimer: I work for an Auth0 competitor, FusionAuth.

Heya, Auth0 is still around! They got bought by Okta in 2021 but still have a free tier and we see them in a lot of bake-offs.

OAuth 2.x and OIDC haven’t changed much. I still use Passport.js with Firebase.
