Firebase Tokens
===============

[](#firebase-tokens)

A library to work with [Google Firebase](https://firebase.google.com) tokens. You can use it to [create custom tokens](https://firebase.google.com/docs/auth/admin/create-custom-tokens) and [verify ID Tokens](https://firebase.google.com/docs/auth/admin/verify-id-tokens).

Achieve more with the [Firebase Admin SDK](https://packagist.org/packages/kreait/firebase-php) for PHP (which uses this library).
