Why should I use with The Idem Series authenticator for identity security?

The Idem Series authenticators provide stronger defense against credential theft. Even if you’re using a conventional username and password verification some phishing sites create fake websites to fool you into entering your verification information and then use this to access your account. The Idem Series authenticators use cryptographic verification; they will only authenticate you when you are signing in to legitimate application websites. They are also password free so they are easy to use and there are no complex passwords to remember.
