Google Cloud Nightscout » FreeDNS user ID
You can use your email address to log into FreeDNS in a browser. However, during the installation phase 2, you will need your FreeDNS user ID.
If you don’t remember your FreeDNS user ID, you can find it by logging into FreeDNS. Your user ID will be displayed at the top right pane.
Alternatively, check the verification email you received when you first signed up for FreeDNS; it includes your user ID.
If you have already completed the installation, you can find your FreeDNS user ID and password on the status page by selecting Login Credentials
at the bottom.
