NCP Authenticator works with 2-Step Verification for your NCP VPN Access or any other online service using the TOTP method to provide an additional layer of security when signing in. Once configured, 2-step authentication protects your account by requiring both your password and an additional passcode, thus adding an extra layer of security. NCP Authenticator will generate these passcodes for you in a convenient way, directly on your smartphone or tablet, without the need for Internet connection. NCP Authenticator does not only operate with a NCP vpn account, but also with accounts from Google, Dropbox, PayPal and all the other providers who implement authentication in this standardized way. For additional security QR codes generated by NCP’s management can enforce biometric authentication for starting NCP Authenticator.
