Can someone help me understand if the Blockclock by nostr:npub12ctjk5lhxp6sks8x83gpk9sx3hvk5fz70uz4ze6uplkfs9lwjmsq2rc5ky is safe from a security perspective? It seems the only way to get it to work is to use my main WiFi user name / password, and the website is http instead of https. It doesn’t pass the smell test to me
