+## Security
+
+By default, MongoDB **does not enforce access control**, meaning that even if you set an admin username and password in the settings of your Pterodactyl server, **anyone will be able to connect to the database without authentication**, and perform any operation.

+> :warning: This is why we recommend to expose your MongoDB database only to your local network, if possible
+
+### Notes specific to the MongoDB 6 egg
+
+The [MongoDB 6 egg](./egg-mongo-d-b6.json) enables access control by default in the `mongod.conf` file, meaning that even if people will be able to connect to your database as guests, [they will not be able to perform any operation, apart from nonhazardous commands](https://dba.stackexchange.com/a/292175)
+
+### :warning: If you know what you are doing, and you really want to disable access control, you can do so by editing the `mongod.conf` file
+
+```yaml
+security:
+  authorization: "disabled"
+```
