Passport is a middleware for express.js. It supports various login types, Basic, Token, Local (username, password), OAuth, OAuth2, etc. We can combine these to allow users to authenticate by signing in with Google, FB, or whatever service with very minimal amount of code. We can also use this to combine external auth services so users can choose to login with one of the selected Strategies, e.g. Google, Twitter.
