Main Features

Secure Password Vault

Store up to 1,000 login credentials & strong passwords in a hardware vault. Input passwords with a single click, thwarting keylogging attacks. Hideez Client software verifies website addresses to prevent phishing.

Passwordless Authentication

The FIDO2 authentication eliminates the traditional threats that come with using a login username and password, replacing it with the FIDO2 passwordless login standard. It protects against common online attacks such as phishing and man-in-the-middle attacks.

Multifunctional Security Key

Generate strong and unique passwords, lock/unlock your PC by proximity, create secure data backups. Generate one-time passwords (OTPs) or use the key as a U2F security key for two-factor authentication.

RFID Door Lock

Are you tired of carrying a bunch of electronic keys from your home, office, gym? Free up space in your pocket by using Hideez Key to open RFID-enabled electronic doors. Note: Hideez Key can store only one RFID at a time.

What are the benefits?

Zero-knowledge Password Vault with 2FA and more

• Compatibility with password-based legacy mode, providing password-based systems with the highest levels of access control protection and usability.

• Secure password vault with a login/password input based on button click and integrated TOTP capability.

• Smart proximity-based authentication and unattended workstation logout.

• Enterprise-ready with Active Directory integration, centralized user provisioning, and incident response handling.

Support for the FIDO U2F and FIDO2 authentication
