OnlyKey DUO - Hardware-based authentication that leaves Yubikey in the dust

Kickstarter announced today by the makers of the OnlyKey.


  • FIDO2 out of the box
  • TOTP (Ex: Google Authenticator)
  • GnuPG signing
  • Plain text password entry
  • 3 methods of touch activating different keys/passwords
  • USB-C and A
  • More…

As a 2yr daily user of their standard OnlyKey i’m comfortable recommending it.


Nice. Just backed this.

I have never had a “security key” thing before.

looks like this is missing yubikey’s PKCSII features, which is fine, but good to know about
