                        When you next log in to your account, you will need your Authenticator App handy to produce

                    <p>
                        In case you lose access to your Authenticator App, please print off or write down these
                        <strong>backup codes</strong> which will allow you to re-gain access to your {{PrettyTitle}}
                        account. Each of these codes may be used <strong>one time</strong> in response to your
                        2FA Authenticator prompt at login.

                        a fresh set of backup codes. Note that re-generating new codes will cause the old ones to no longer work!

                    <p>
                        To set up Two-Factor Auth, you'll need to download and install a compatible
                        Authenticator App on your device. Some suggestions for apps that are compatible
                        with {{PrettyTitle}} are as follows:

                    <h3>Add {{PrettyTitle}} to your Authenticator App</h3>

                    <p>
                        When you have your Authenticator App ready, click on its "Add a new site" button and scan
                        the following QR code to enroll your device for {{PrettyTitle}}:
                    </p>

                    {{ToHTML .QRCode}}

                    <p>
                        Alternatively (if you can't scan the QR code), you may copy and paste this secret text
                        in to your Authenticator app:

                        After scanning the QR code (or copying the secret key) into your Authenticator app, you
                        should be able to generate temporary six-digit authentication codes.
                    </p>

                    <p>
                        Test that you have enrolled your authenticator correctly by entering the current six-digit
