Crate humphrey_auth

source ·
Expand description

Web applications commonly need a way of authenticating users. This crate provides an easy and secure way to do this, integrating with Humphrey using the AuthApp trait and allowing complete control over the database users are stored in. Humphrey Auth does not come with a database, but the AuthDatabase trait is implemented for Vec<User> to get started. For a production use, you should use a proper database and implement the AuthDatabase trait for it.

If a JSON representation of users is useful for your database, you can enable the json feature which provides JSON serialization and deserialization for User and Session using the Humphrey JSON crate.
