PocketKey+ FIDO Certified USB Security Key with NFC

ACS’s PocketKey+ provides users the experience of secure and swift passwordless online login. It allows individuals, enterprises, and government-scaled agencies to substitute passwords with multi-factor authentication or two-factor authentication, reducing reliance on static passwords.

The device is certified by the FIDO Alliance [FIDO®] and is compliant with FIDO U2F and FIDO2 protocols.  The device’s cryptographic security model terminates any likelihood of phishing, password/identity theft and repetitive attacks. User tracking can also be prevented by storing FIDO cryptographic keys on device and creating unique keys for each website.

PocketKey+ is available as a USB Type-C with NFC function, and is designed with a mechanical switch. The switch is essential for acknowledging user presence as it ensures that the user is physically present in order to interact with the application.

It is also compatible with operating systems such as Windows®, Linux®, macOS and Android™, as well as major web browsers: Chrome™, Safari®, Microsoft Edge® and Firefox®.
