  • Does your bank or credit card company use two-factor authentication, either online or via telephone banking? If so, what form does it take?
  • What kind of two-factor authentication is used by shops that you use, either online or in the high street?
  • Can you find examples connected with your work, for example to access the company VPN or different areas of the building?

Write a short comment about the type of methods and devices you came across that offer two-factor authentication in the space below. Then discuss the questions with colleagues and add to your notes any other methods and devices you have learned about.
