Step 2: Next, install Google Authenticator® App on your mobile phone. See how to install it here.

Step 3: Check the “Enable two-factor authentication” option in the “User Preferences” page, the “Account Information” tab and click on “Save changes” button. Note that the current password is required to make changes.
At this step, you need to connect Tiki and the Google Authenticator® application by scanning the QR Code generated in the “User Preferences” page. Click on "Show QRCode" to display the QR Code, scan it using the application you installed in step 2.
