QR stands for "Quick Response.

While they may look simple, QR codes are capable of storing lots of data. But no matter how much they contain, when scanned, the QR code should allow the user to access information instantly – hence why it's called a Quick Response code.

Scanning a QR code using your device is straightforward:

• Open the QR reader application or the camera on your smartphone.
• Point it at the QR code – you should be able to point your camera from any angle and still receive the necessary information.
• The data will be instantly shown on screen – for instance, if the QR code contains contact details, your phone should instantly download these.

Download and install your choice of time-based one-time password (TOTP) generators. Here's a good article from Gizmodo covering their favorite options, but popular choices around the office are:

• Authy
• 1Password
• Google Authenticator

When prompted by the app, scan or drag and drop this screen's QR code into your authenticator.
