🔐 Access Protection

TIP

If you expose CoolerControl beyond the local loopback interface, it is strongly recommended to set your own password to protect your devices from unauthorized changes.

CoolerControl includes basic authentication to prevent unintended control. By default, the daemon binds to the local loopback interface and starts with a default password. You can change this from the Access Protection menu to set your own password. In typical single-user setups this is sufficient, but on multi-user systems setting a unique password adds an extra layer of protection against accidental or intentional changes.

WARNING

Do not expose the daemon openly on a network without additional protections. If remote access is required, set a strong password and use host firewall rules or a secure tunnel (e.g., SSH port forwarding) to restrict access.

To reset the password back to the default, run:

sudo coolercontrold --reset-password

TIP

If the password prompt appears and you have not set a custom password, close the dialog and click "Login" in the Access Protection menu to sign in with the default password. This should be a rare, one-off occurrence.
