As a counterpoint, learning the basics of a good OAuth library or service like oauth2-proxy, auth0, next-auth or keycloak is well worth your time as a developer. Once you get over the initial learning curve, it’s almost as easy to add to a project as basic auth. You don’t need to reinvent the wheel with each project, building login pages and database code - other people have done the work for you - and you can create a more usable and professional experience for your users.
