Multi-Factor Authentication Examples
How Does MFA (Multi-Factor Authentication) Help?
Well, multi-factor authentication looks at, as the name implies, multiple factors to authenticate a user. One of the most common ways to enable convenience while enforcing multiple-factor authentication is to have a certain fingerprint for an authenticated device that’s logging in. The fingerprint, or device’s identification as an authorized device, is typically identified by its IP address and machine characteristics (e.g., the browser, browser version, machine operating system, the user’s Geo IP, and other information).
This composite fingerprint of the device is created so that if the device is not recognized for a user, then we give them multiple factors to authenticate their login. Username and password are a good starting place, but then they’ll be required to click a link or get an ID from their email or phone. They may also need to answer security questions or use a thirty-second rolling key value that they have to provide. The user could also take a voice call and input data from the voice call. They can select a picture, color, a series of phrases that they have to enter, etc. There are many ways to require users to complete multi-factor authentication.
