FIDO Alliance's Universal 2nd Factor (U2F) is a new and promising approach to replace passwords. The FIDO Alliance comprises of many players but so far only Google website seems to support it. Are there other websites I can use to login with my U2F token?
See www.dongleauth.info It contains a list of websites, self-hosted software and USB dongles compatible to U2F (as well as One Time Passwords).
