Library to generate API tokens without database

You might not have access to a full-fledged database but you could always try using a sqlite backend. Store all of your tokens inside a table in the sqlite file. Use spark command line to manipulate that database for creation/deletion/etc of tokens. When a request comes in, check the for the Bearer token header and compare against your sqlite database, if authorized proceed, if not issue appropriate rejection. If you're referring to something like a JWT the process would be more involved, but for a basic random token you can use any sort of time based uuid or just bin2hex(random_bytes()).

Great idea! I'll implement a sqlite db in the web app

I've installed (through composer) this library. It allows to generate, validate, etc. JWT

So I'll store those tokens in the sqlite

Thanks again
