## How does 2FA work in Tycoon?

Tycoon supports 2FA via authenticator apps (Google Authenticator, 1Password, Authy, Microsoft Authenticator). After entering your password, you enter a six-digit code from the app.

## How do I turn it on?

Go to **Settings → Account → Security**, click **Enable two-factor authentication**, scan the QR code with your authenticator app, and enter the code it generates. Save the recovery codes that appear — you'll need them if you lose access to your authenticator app.

## Can I turn it off?

Yes. The same screen has a **Disable** option. You'll need to enter your current 2FA code to confirm. 2FA is per-account, not per-workspace.
