Based on proven One-Time Pad principles from the Cold War, TokenOne is the strongest form of software-based Two-Factor Authentication (2FA) for organizations of all sizes. How Is TokenOne Different From Other Authentication Systems? The key differentiator to other authentication services is that TokenOne proves user presence. We provide genuine strong Two-Factor Authentication as both factors are strong. There are three accepted factors in Authentication: With TokenOne you never reveal your secret PIN – so the knowledge factor remains strong. Unlike other solutions that rely on the user entering a ‘secret’ (usually a password) to prove they know it, TokenOne changes the knowledge factor paradigm by enabling proof of the knowledge factor without ever revealing it. This makes the TokenOne PIN a ‘zero-knowledge password proof’ and sets a new standard for Authentication. The second factor, the possession factor, is your smart device. This has been profiled and must also be present to prove you are an authorized user. With TokenOne Authentication both factors are strong. TokenOne allows organizations to prove who is accessing your site or service. This is vital not only for the security of sensitive information but also for compliance.
