Node Login

Node login is only required if you want to register your Lightning node on Amboss. Exploring Space, browsing the network explorer, viewing channel analytics, and monitoring nodes all work without logging in.

To register your node, you’ll need to sign a message using your node to prove ownership. You’ll also need at least one public channel that has been open for a few days so we can find your node on the Lightning Network graph.

After logging in, you can manage your connected nodes at Space Settings → Connect and customize your node profile .
