Shield

Shield is a comprehensive security solution for Lucky framework. It features robust authentication and authorization, including user registrations, logins and logouts, password resets and more.

Shield is secure by default, and exploits defence-in-depth strategies, including the option to pin an authentication session to the IP address that started it -- the session is invalidated if the IP address changes.

User IDs are never saved in session. Instead, each authentication gets a unique ID and token, which is saved in session, and checked against their corresponding salted SHA-256 hashes in the database.

When a user changes their password, Shield logs out the user on all devices (except the current one), to ensure that an attacker no longer has access to a previously compromised account.

Shield supports API authentication, with regular passwords or with user-generated bearer tokens. In addition, all authentication actions that can be performed in the browser have their API equivalents.

Shield is designed to be resilient against critical application vulnerabilities, including brute force, user enumeration, denial of service and timing attacks.

On top of these, Shield offers seamless integration with your application. For the most part, include a bunch of modules in the appropriate classes, and you are good to go!
