_Note: Attempting to run sway this way without this being configured correctly will probably leave your computer in an unresponsive state, requiring a reboot_
To have sway run as root in order to gain access to the resources you need, you must set the setuid bit on the sway executable:
```
chmod +s /usr/bin/sway
```
Sway will fork into a minimal slave process to keep these privileges, while dropping its own. As with any program, using setuid has serious security implications.
