<GenerationInfo sourceFile="packages/core/src/config/auth/native-authentication-strategy.ts" sourceLine="36" packageName="@vendure/core" />

This strategy implements a username/password credential-based authentication, with the credentials
being stored in the Vendure database. This is the default method of authentication, and it is advised
to keep it configured unless there is a specific reason not to.

```ts title="Signature"
class NativeAuthenticationStrategy implements AuthenticationStrategy<NativeAuthenticationData> {
    readonly name = NATIVE_AUTH_STRATEGY_NAME;
    init(injector: Injector) => ;
    defineInputType() => DocumentNode;
    authenticate(ctx: RequestContext, data: NativeAuthenticationData) => Promise<User | false>;
    verifyUserPassword(ctx: RequestContext, userId: ID, password: string) => Promise<boolean>;
}
```
