If you need to, you can manually do that from your account page, and subsequently login again on each of your devices. > [!question]- Q2. I enabled, then disabled 2FA. I would like to set it up again. Can I use the original QR code or setup key? > No. > > You will be provided a new **QR code** and new **Setup key** every time you initiate a new setup of 2FA. > [!question]- Q3. I have enabled 2FA.
