For The Consumer
Think of knowledge-based security as a set of disconnected sites. When one level becomes ineffective, another level is added. The pin becomes a password and passwords then need security questions to authenticate them. This is hard and stressful work for the customer, and it puts them further and further away from completing their intended task.
Fortr3ss does away with all this. It uses the users unique voiceprint for authentication. Fortr3ss uses a unique combination of numbers presented to the user so they never have to remember their passphrase. It’s more natural and more secure than fingerprints or retina.
