# Setup 2FA

> Generate a TOTP secret and QR code URI for setting up two-factor authentication

<Note>
  This endpoint requires a valid Bearer token in the `Authorization` header.
</Note>

Initiates two-factor authentication setup for the merchant's account. Returns a TOTP secret and an `otpauth://` URI that can be rendered as a QR code for authenticator apps like Google Authenticator or Authy.

After scanning the QR code, the merchant must call [Verify 2FA](/api-reference/auth/verify-2fa) with a valid code to complete the setup.

### Example Response (200)

```json theme={null}
{
  "secret": "JBSWY3DPEHPK3PXP",
  "otpauthUrl": "otpauth://totp/OpenPay:admin@acmepay.com?secret=JBSWY3DPEHPK3PXP&issuer=OpenPay",
  "qrCode": "data:image/png;base64,iVBORw0KGgo..."
}
```

<Warning>
  The `secret` is shown only once during setup. If the merchant loses it, they will need to disable and re-enable 2FA.
</Warning>
