The 4th generation of the YubiKey, the YubiKey 4, is based on the body of the YubiKey Edge. This latest version allows us to unleash the 4th generation YubiKey’s full power with 4096 bit RSA in the OpenPGP capability, and touch-to-sign, with proof of user presence for both PIV and OpenPGP.
For more information about the YubiKey 4, as well as the YubiKey 4 Nano, see the product page.
Note: We no longer offer the YubiKey Edge for sale on our web store or Amazon. If you still require the YubiKey Edge, contact Sales for large volume orders (500+).
