I read the docs of redwood on “Authentication”, it seems that all of the ways are not independent, they all need a third-party provider.
I need an independent authentication way like this community program —— Discourse，it has two features:
1、 It includes signup and signin with email.
2、 It does not depend on a third-party provider.
Is it possible?
It’s definitely possible to roll your own auth solution. You might want to check out this thread for an example: Custom github JWT Auth with Redwood Auth
An example you’re looking for is probably here:
And code from luca https://github.com/liberatiluca/redwood-db-auth
