An account is optional. Here's exactly what signing in does — and what stays on your device.
No. Capturing, annotating, recording and saving files all work without signing in. An account only unlocks optional extras: cloud sync and shareable links across devices.
Sign in with Google or email and password from the extension popup. You authenticate on the website — which also handles two-factor authentication — and the extension connects itself automatically. There are no API keys to copy and paste.
Signing out from the popup disconnects the extension and signs you out of the website too.
Protect your account with two-factor authentication and review active sessions from the Security page in your dashboard.
