Google released two-factor for GMail in 2011 to generate one-time login tokens and by adding two-factor authentication (2FA) to your web application will increase the security of the data of the user. You just need a smartphone to download the “Authenticator” mobile app for scanning the QR Code generated after login or registration.
- Your PHP application will generate a QR code, users scan with their mobile phone camera to add the profile to the Google Authenticator application.
- After that the authenticator application will generate a new code within every 30 seconds for using the second authentication section to the application in PHP.
- First, we create the registration form and a login form. After the user registers to the system, we will generate the QR Code and validate it through Google Authenticator App.
Here, we have successfully created a database, now put JS and CSS files into the project directory.
You can use include (‘class/userclass.php’); to save information in the database. And, it require_once ‘googleLib/GoogleAuthenticator.php’; to generate barcodes with googlelib.
To decode this barcode, you will need a Google authenticator application (Android / iOS). Below is the code for the Index.php file.

Once you see your barcode after login then scan the barcode with Google authenticator application, and save the generated number to insert into the text box.
