[keycloak-user] Permanent API key?

[Corentin Dupont]

Hi guys,
Is it possible to have a permanent access token, or API key, that I can
store on the client of my API?
Or maybe I need to store my login/password on the client and retrieve a
normal access token from the device?
in my use case, I have remote devices writing to my API. Those devices are
not easy to update.

I see that some services uses an API key, passed as a query string, that
seems to be permanent.
For example ThingSpeak:

Is this possible with Keycloak? I.e. permanently granting access to some
device?
