However, side channel leakage is an unsolved problem in industry and academia. A true random number generator is used to create unpredictable keys. Any secret information cannot be read or duplicated. The security level is about the same as a modern car key. Discussion for hardware design and usage is happening here, feel free to chip in. ![]() A new open source FIDO 2 token is being planned (with support for USB, Bluetooth, and NFC). It has more flexibility and support for password-less login. Redesign / FIDO 2įIDO 2 protocol is replacing U2F. The token should be durable enough to survive on a key chain for years, even after going through the wash.Ĭheck out the wiki for more on how to build your own. It ends up being $35 for programmer and ~$5/board. You just need to order theĨ SMT parts, $1.13-$3.5 per PCB, and programmer. The latest version uses key derivation and has no limit on registrations. It works with Google accounts, Github, Duo, and anything else supporting U2F. U2F Zero is an open source U2F token for 2 factor authentication. This project is superseded by the open source FIDO2 token, Solo. This project has been replaced by Solo security key ![]()
