Is Superhuman Docs Browser Extension safe?

Clean risk

Coda Browser Extension creates a Coda API token on request and stores the bearer token in Chrome sync storage.

When the user creates a token from the popup, the service worker reads the coda.io csrf_token cookie and posts to coda.io/internalAppApi/account/tokens with account credentials included. It saves the returned token secret as codaClipperKey in chrome.storage.sync and later uses it as a Bearer token for Coda API requests.

Shared hosts - 3 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
