For your consideration, more of a style comment.

I think we should first define an array with all of these values, then infer a union type out of it. This will remove

const authMethods = ["password", "github.com", "google.com"] as AuthMethod[];

in getPreferredAuthenticationMethod, which would make it easier to expand authMethods (only need to change the array instead of both the array and the type).

Suggested change

	export type AuthMethod = "password" | "github.com" | "google.com";
	const authMethods = ["password", "github.com", "google.com"] as const;
	export type AuthMethod = typeof authMethods[number];

And remove authMethods definition in getPreferredAuthenticationMethod.

Depends on previous review comment.

Suggested change

	const hasRemainingAuth = [
	isUsingPasswordAuthentication() && options.authMethod !== "password",
	isUsingGithubAuthentication() && options.authMethod !== "github.com",
	isUsingGoogleAuthentication() && options.authMethod !== "google.com",
	].find((it) => it);
	const hasRemainingAuth = authMethods.some((authMethod) => isUsingAuthentication(authMethod) && options.authMethod !== authMethod);

Need to export isUsingAuthentication and authMethods, also remove isUsingGithubAuthentication and isUsingGoogleAuthentication.
