Is Authenticator safe?

Clean risk

Authenticator embeds OAuth client secrets for Google Drive and Microsoft OneDrive in plaintext within its extension bundle.

The extension stores OAuth client_secret values for both Google Drive and Microsoft OneDrive directly in its JavaScript files (background.js and popup.js). These secrets are transmitted to Google and Microsoft token endpoints during authorization and token refresh flows. Anyone who unpacks the extension can read these credentials, which are confidential application-level secrets not intended for client-side distribution.

What this publisher told the store about itself, and the other listings that told it the same thing.

Shared hosts - 1 hostname

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.

Where it sends data
