Authentication plugin for Yesod.
This package is the Yesod.Auth.HashDB plugin, originally included as part of yesod-auth, but now modified to be more secure and placed in a separate package.
It provides authentication using hashed passwords stored in a database, and works best in situations where an administrator is involved in setting up a user with an initial password.
The complete login process, including a default form, is implemented by this plugin, but the application developer must design the interfaces for setting up users and allowing them to change their own passwords, since only the low-level password-setting functions are provided by this package. (Note that other authentication plugins may be more appropriate if you wish to use email verification to set up accounts).
