FAQ

Frequently asked questions

A signed JWT with license data is generated and the client stores it locally. Even offline, the license token can be cryptographically verified using a public key.

To ensure the client has the latest license information, the token needs to be refreshed periodically. When the device is online, it can refresh its token by requesting a new one from the Keyforge API.

You can customize for how long a token is valid. For very long offline periods, you can skip expiration checks if needed, but this is not optimal.

Any language with a JWT library works. JWTs are an open standard, so you are not locked into our SDK.

No. License tokens are issued by our API and verified locally on the client. You do not need to run any server-side code.
