What is an example of a web application using multifactor authentication?
- A user logs on to an online shopping website and uses a credit card to make an order.
- Teleworkers are required to establish a VPN connection to the company before logging into the company internal web server.
- A user attends a large conference and tries to access Google Gmail at the conference site. The Gmail service sends a verification code to the smartphone of the user.
- A network administrator needs to swipe a card in order to access the corporate server room.
Explanation: When multifactor authentication is implemented, two or more different authentication methods are used. Multifactor authentication is often used when accessing online services. For example, when a user wants to access a service, an authenticator application sends a code called a one-time password (OTP) to the registered phone or email address of the user. The user must supply the correct account username and password plus the OTP code to authenticate.
