It depends on what your needs are. If you need simple auth for a single application, most languages have libraries/frameworks that cover most of your needs and are relatively trivial to implement. In .NET land you have Identity[0] for example. You just need to look up what is the most popular option for the tech you're using and if it ticks all your boxes.

If you're looking for a full fledged service that offers SSO and that you can self host (or cloud) with SDKs for most of the popular languages out there, then I'd recommend to look at Ory[1].

The problem with simple auth is that it gets complicated with TOTP/2FA which I believe is necessary nowadays. I think you are right so see what is most popular with the language (python in my case) and stick to it, but there are lots of Identity providers our there and they have different pricing schemes. I will definitely check out ory.sh I have not heard of them before.
