如何手动＆QUOT;登录＆QUOT用户;使用WebSecurity + SimpleMembership？

我想使用WebSecurity + SimpleMembership，但实现通过自定义/替代身份验证方法的能力（可选）登录用户。

I'd like to use WebSecurity+SimpleMembership, but implement the ability to (optionally) login users via a custom/alternative authentication method.

WebSecurity.Login只有一个方法签名，既要有一个用户名和密码。我想跳过密码检查，例如：

WebSecurity.Login only has one method signature, which requires both a username and a password. I'd like to skip the password check, e.g.:

if (MyCustomAuthenticationMethod.Authenticate(username, customData)) {
    WebSecurity.Login(username); // Login without password check, method doesn't exist though
}

我想定制的auth-方法是可能给OAuthWebSecurity存在，但我不知道如何去实现我自己的。

I assume custom-auth-methods are possible given OAuthWebSecurity exists, but I'm not sure how to go about implementing my own.
