Two-factor authentication

Add a second login step with an authenticator app. A leaked password alone won't get someone in.

Two-factor authentication (2FA) adds a second login step using a time-based code from an authenticator app on your phone. With 2FA on, even a leaked password won't get someone into your account.

Turning it on

Settings → Security → Two-factor authentication → Enable.

  1. Scan the QR code with an authenticator app — Google Authenticator, Authy, 1Password, Microsoft Authenticator, or any TOTP-compatible app.
  2. Enter the 6-digit code from the app to confirm.
  3. We generate 8 single-use backup codes — print or save them somewhere safe. Each one works exactly once if you lose access to your authenticator.
  4. 2FA is now on.

From your next login, after your password we'll ask for the 6-digit code.

If you lose your phone

  • Backup code at the 2FA prompt. Each one works once.
  • Email recovery — at the prompt, click "Lost your code?" and we'll email a magic link. The link signs you in once and lets you disable 2FA or set it up on a new device.

If you've lost both, contact support — be ready to verify identity via your accounting records.

For accountants on client accounts

2FA is on YOUR account, not the client's. When you act-as a client, you're still you with 2FA already verified — no extra step.

Turning it off

Settings → Security → Disable. Requires a current 2FA code or backup code to confirm — prevents someone with just your password from removing the second factor.

When 2FA is required

Recommended for everyone, mandatory for:

  • ADMIN role on the platform.
  • Verified accountants after KYC approval.
  • Anyone managing real customer billing.
