Security and privacy
Why no password?
Passwords are frequently reused and leaked. One-time codes and passkeys reduce that risk and remove password reset friction.
How is cloud data protected?
Cloud data is scoped to your signed-in account and is only shared when you explicitly create a temporary invite code.
Why am I being asked for a PIN?
That prompt is usually your device security check (for example Windows Hello, a device lock PIN, or key verification), not an app password. See passkey prompt details.
