 # Frequently Asked Questions
+
+## Logging In
+
+### I can't login to Cachet, can you reset my password?
+
+We don't have access to your installation, but you are able to reset your password manually:
+
+Follow the commands below, replacing `:userId` with the ID of your user. The initially created user will be `1`.
+
+```bash
+$ cd /var/www/ # the root of your Cachet installation
+$ php artisan tinker
+Psy Shell v0.8.8 (PHP 7.1.6 — cli) by Justin Hileman
+>>> $user = CachetHQ\Cachet\Models\User::find(:userId);
+=> CachetHQ\Cachet\Models\User {#865
+    id: 1,
+    username: "test",
+    email: "test@test.com",
+    api_key: "9yMHsdioQosnyVK4iCVR",
+    active: 1,
+    level: 1,
+    created_at: "2015-07-24 13:42:10",
+    updated_at: "2015-07-28 15:12:55",
+}
+>>> $user->update(['password' => 'New Password']);
+>>> exit
+```
+
+## Databases
+
+### Does Cachet support database X?
+
+Cachet has built-in support for:
+
+- MySQL
+- SQLite
+- PostgreSQL
+- SQL Server
+
+### Can Cachet support database X?
+
+Cachet is built on the [Laravel](https://laravel.com) framework. By default, Laravel supports the databases listed above but can be extended to support new drivers, so whilst technically possible, it's not within scope of the core team to provide support.
+
+Each new driver requires additional support, testing and maintenance to retain compatibility with the features we want to build into Cachet in the future.
+
+## Support and troubleshooting
+
+### Do you offer paid support for Cachet?
+
+We have been experimenting with paid support for Cachet at a limited scale. Cachet is not a full-time job, so our time is low and we cannot yet promise that your support request will be dealt with immediately.
