This simple CypherKey application can be used to authenticate with participating CypherKey Authentication sites and achieves genuinely strong Two-Factor Authentication (2FA) as an alternative to passwords, SMS of One-Time PINs (OTPs) or tokens.

CypherKey allows users to:

- register their phone to prove the presence of something they have, and
- mentally scramble their self-selected PIN so it’s never revealed or entered when proving the PIN is something they know.

Since the user’s PIN is never revealed, the same PIN and phone can be used safely for multiple participating sites and accounts for optimal convenience while avoiding the risks of password re-use or similarity.

Prerequisites:

In order to use this application, your company must have an active CypherKey Authentication solution or had been issued with a demo account. This application does will not register your account or scramble your PIN without an active CypherKey Authentication deployment.
