Is Mesh safe?

Low risk

Mesh lets any site trigger its web-accessible iframe to identify the signed-in account to Segment.

Mesh exposes an iframe to all websites and listens for postMessage events without checking the sender. A page can send a userAuthedWithMesh message that makes the extension read stored auth tokens, fetch the Mesh account profile from api.me.sh, and send traits such as user ID, name, username, email, and extension version through Segment analytics.

Where it sends data
