This is a market created by the supabases and it’s no code cousins. I frankly always considered auth so simple and fundamental, with best practices so well known that I never saw the need to use a SaaS for user auth. I guess if you want to offer all the auth methods that this library is useful and saves a lot of time.
Absolutely wild take. Auth is most definitely not simple, nor are best practices well known, based on number of auth-related vulnerabilities published.
You mean that for toying, personal use or hobby projects, right? Otherwise people get jaw drops or facepalms.
As someone who has been at a company where for various reasons, we decided to "roll our own auth", I would have to disagree here. Don't reinvent the wheel if you can avoid doing so.
