Is 2FAS Auth - Two Factor Authentication safe?

Clean risk

This extension fills two-factor authentication tokens from the 2FAS Auth mobile app in your browser.

It pairs your desktop browser with the 2FAS Auth app on your phone so you can confirm logins and enter 2FA tokens without retyping them. After you pair a service with the app, it selects the matching token for future logins.

Shared hosts - 2 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.
