allow one concurrent user per login with JWT

Question

We developing an application with Laravel/PHP and we want to use an pay-per-user pricing model. For that we have to ensure that an account can only used by only one concurre

Answer 1

Only answer i can think of:

On login: "User" in your DB has a value = activeJwt

User logs in and JWT token is created, copy the JWT string to value activeJWT in your DB and send it to user. If you login on another device same deal, and the activeJWT value is changed

On all requests that require login match users JWT-string and activeJWT, if they dont match it means another device logged in after making the old token useless.
