I'm building a little side project (web app) but I really don't want to roll my own login flow. I'm also not a fan of social login. What are you using for your little side projects?
Maybe take a look at htaccess/htpasswd. I've been setting up docker containers and have proxied them using traefik. Most of them have built in auth of some kind but for those that don't, htaccess seems to be doing the job. Not sure about the security implications though.(I've mostly used it on a local network so security was not a concern for me) This works well for services that you want to use for yourself only.
