If it's decided that this bundle is "the JWT solution for Symfony", then we could even go for adding jwt too as an alias.

[ogizanagi]

I wanted at first, but the bundle is a solution for setting a jwt authentication, not for consuming external jwt tokens for instance (even if it depends on libraries that will probably do natively).

Indeed, the bundle is written on top of libraries like lcobucci/jwt, it is only about authentication while jwt can be used in different contexts. 👍 for jwt-auth

Thank you @ogizanagi.
