    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.


JSON web tokens are string-based tokens that are used to authorize users. The most important point of JWT is the ability to store it securely on the client-side, thus being able to scale horizontally without worrying about a dedicated authorization server. JWT Tokens holds claims that can be used to identify a user (name, role...). Each token has an expiration date; after that time, it becomes inactive.

EasyJWT sub-system:

  • Create JWT Generator
  • Create JWT Verifier

JWT Generator:

It could be used to generate signed JWT tokens with custom headers & claims. It supports a bunch of claims such as iat,exp,nbf in addition to custom claims using blueprints.

JWT Verifier:

It could be used to verify generated JWT Tokens and extract claims out of the token. Custom verification conditions could be applied through blueprints.
