# OAuth2 with Password (and hashing), Bearer with JWT tokens { #oauth2-with-password-and-hashing-bearer-with-jwt-tokens }

Now that we have all the security flow, let's make the application actually secure, using <abbr title="JSON Web Tokens">JWT</abbr> tokens and secure password hashing.

This code is something you can actually use in your application, save the password hashes in your database, etc.
