Imagine a large house, with multiple entrances. A well-balanced structure will have a combination of storm doors, sliding glass doors and wood fixtures all offering strong security as well as convenient access into the home. It’s rare to find a house with just one type of door.
In a mobile application, security checkpoints act like doorways into the software for customers. And just like architects have many different types of doors to choose from, developers have multiple biometric—or biological—options to layer on top of an application for mobile identity verification.
These can include:
- Password and username combinations
- Security questions
- Facial, iris, fingerprint or Voice biometric authentication scanners
Of course, these solutions all offer varying levels of convenience and security. Generally speaking, it’s difficult to say that any one is better or worse than another. For example, voice biometric identity verification is widely regarded as the most secure option of all of these; however, there are some environments where voice biometric authentication can actually be inconvenient for users — like in a noisy environment where it can be difficult for a microphone to pick up a clear voiceprint. In this case, a customer would be more apt to use a fingerprint or iris scanner to log into an account.
So as a developer, it’s best to take a multimodal approach to mobile identity verification. Offer your customers or coworkers a variety of options for logging in securely, and they will be more apt to actually turn them on and use them instead of bypassing them out of convenience. There is no need to be exclusive when it comes to biometric authentication.
