Whenever I Google things like "php authentication library" I continue to come up with a ton of results of authentication libraries designed for Code Igniter.

What I am looking for is things like the following,

  1. A robust library that handles login, logout, registration, login retrieval etc...
  2. Very secure authentication possibly using sha-256+?
  3. Library that can be integrated into any code, framework or not
  4. Active project and community so that I can rely on it in the future.
  5. Compatible with MySQL
  6. Maybe some things I do not know about?
php mysql authentication
