Key Fobs and Dual-Frequency RFID Cards as FIDO2 Security Devices

Key Fobs and Dual-Frequency RFID Cards for FIDO2 Authentication

Key fobs and RFID access cards have long been used to open office doors and restricted areas. With FIDO2 authentication becoming a new standard for digital access, these physical credentials can now do more than just unlock buildings — they can also unlock computers, applications and corporate platforms.

By combining physical security with passwordless login technology, companies can issue a single credential that protects both the physical and digital workplace.

Why Key Fobs Are Ideal for Passwordless Login

A key fob equipped with RFID or NFC technology can be registered as a FIDO2 security device. Once paired with a user account, it can authenticate login sessions simply by tapping it on a compatible reader or workstation.

Compared to passwords, key fobs offer:

  • Immediate authentication without typing
  • Strong resistance against phishing or remote attacks
  • No shared secrets stored on servers
  • Easier onboarding and offboarding for employees

They are compact, durable, and easy to attach to keychains or lanyards — making them practical for daily use.

What Makes Dual-Frequency RFID Cards Valuable?

Dual-frequency RFID cards support multiple access protocols at once, allowing them to function in:

  • Existing building access systems (125 kHz or HF)
  • Modern FIDO2-compatible digital readers (13.56 MHz NFC / ISO standard)

This flexibility enables companies to upgrade authentication systems gradually, without replacing their entire infrastructure. A single badge can open a door and log into a workstation, depending on how it is programmed.
