Hideez Key 5: one RFID key fob for doors, turnstiles and your computer
Hideez Key 5 carries a contactless access credential and a FIDO2 security key in one small device. Your team opens the office door and signs in to work with the same key. Hideez Key 5 is available now.

What you get with the built-in credential
Opens doors and turnstiles
A built-in MIFARE credential works with standard access control readers.
Works on its own
The tag is passive and separate from the key electronics, so door access does not depend on the key firmware.
Keychain or wristband
One housing, 33.6 × 33.6 × 10.5 mm and 11 g. It fits a key ring, a lanyard or a standard 20 mm strap.
Your credential type
MIFARE Plus EV2 as standard. MIFARE Classic, MIFARE DESFire or 125 kHz RFID (HID, EM-Marine) on order.

A separate tag inside the key
The access credential is a passive tag powered by the reader. It does not share an antenna or a data line with the key’s main board, and it is provisioned with the standard tools of your access control system. FIDO2 over NFC uses the key’s own radio, so both work in one housing without switching modes.
How to get started
Choose the credential
Standard MIFARE Plus EV2, or tell us which type your readers use.
Add the keys to your system
Your access control provider enrolls each key as it does any card.
Roll out
Employees use one key for the door and for sign-in.
The video shows an earlier Hideez Key. The door credential works the same way in Hideez Key 5.

The same key signs in to work
Hideez Key 5 also works as a FIDO2 passkey for Microsoft Entra ID, Google and hundreds of services. With Hideez Workforce Identity Server it locks the Windows PC when the user walks away and unlocks it on approach.
FAQ
Which door systems does it work with?
Any system whose readers support the credential type of your key: MIFARE Plus EV2 as standard, MIFARE Classic, MIFARE DESFire, or 125 kHz HID and EM-Marine on order.
Does the door credential need Hideez software?
No. The credential is enrolled with the tools of your access control system.
Can I order a different credential type?
Yes, from 1,000 keys. For smaller quantities we agree it individually.
Is it a FIDO2 key and a door key at the same time?
Yes. They are two independent systems in one housing.
Can I wear it on the wrist?
Yes. The housing takes a standard 20 mm watch strap. The strap is sold separately.
I have an earlier Hideez Key. How does its RFID work?
Earlier models have a 125 kHz module (HID or EM-Marine) and hold one code at a time, set in the Em-Marine standard by default. Hideez Key 5 uses MIFARE.
