Why it's Secure

Hardware Random Number Generator

A TRNG is used on chip to ensure high entropy keys get generated during registration.

Write Only Keys

Keys are generated on an off chip peripheral and live in write only memory. Nothing can read them except the peripheral itself.

Tamper Resistance

Atmel secure chip includes temperature and voltage tampering sensors.

Open Source

Because the source is open, there is confidence there are no backdoors in the source code.

My U2F Token does not work with Firefox (Check-only command 0x07)

Make sure Firefox is updated to the latest version (at least FF60). If it still does not work, email support and you will be refunded. There was a faulty batch made around start of 2018 that has this issue. U.S. market is fine but EU market is still being replaced.

Note that stock in U.S. and EU is currently up-to-date and working.


Can I reprogram my U2F Zero?

Yes, refer to the wiki on the Github repository.
