You can find a complete sample of what you're trying to do in the Nodepad application by Alex Young. The 2 important file you should take a look at are these 2:
https://github.com/alexyoung/nodepad/blob/master/models.js
https://github.com/alexyoung/nodepad/blob/master/app.js
您可以在Alex Young的Nodepad 应用程序中找到您尝试执行的操作的完整示例。您应该查看的 2 个重要文件是以下 2 个：
https: //github.com/alexyoung/nodepad/blob/master/models.js
https://github.com/alexyoung/nodepad/blob/master/app .js
A part of the model look like this:
模型的一部分如下所示：
User = new Schema({
'email': { type: String, validate: [validatePresenceOf, 'an email is required'], index: { unique: true } },
'hashed_password': String,
'salt': String
});
User.virtual('id')
.get(function() {
return this._id.toHexString();
});
User.virtual('password')
.set(function(password) {
this._password = password;
this.salt = this.makeSalt();
this.hashed_password = this.encryptPassword(password);
})
.get(function() { return this._password; });
User.method('authenticate', function(plainText) {
return this.encryptPassword(plainText) === this.hashed_password;
});
User.method('makeSalt', function() {
return Math.round((new Date().valueOf() * Math.random())) + '';
});
User.method('encryptPassword', function(password) {
return crypto.createHmac('sha1', this.salt).update(password).digest('hex');
});
User.pre('save', function(next) {
if (!validatePresenceOf(this.password)) {
next(new Error('Invalid password'));
} else {
next();
}
});
I think he also explains the code on the dailyjs site.
我想他也在dailyjs 网站上解释了代码。

I wrote a boilerplate projectto do exactly this.It supports account creation, password retrieval via email, sessions, local cookies for remembering users when they return and secure password encryption via bcyrpt.
我写了一个样板项目来做到这一点。它支持帐户创建、通过电子邮件检索密码、会话、本地 cookie 以在用户返回时记住用户并通过 bcyrpt 进行安全密码加密。
There's also a detailed explanation of the project's architecture on my blog.

For an easy way to get started take a look at ExpressJS+ MongooseJS+ MongooseAuth.
有关入门的简单方法，请查看ExpressJS+ MongooseJS+ MongooseAuth。
In particular, that last plug-in provides a standard simple way to do logins using several different authentication methods (Password, Facebook, Twitter, etc.)
特别是，最后一个插件提供了一种标准的简单方法来使用几种不同的身份验证方法（密码、Facebook、Twitter 等）进行登录。
