Key piece IMO
Wave’s service enables users to log in to web services securely without a username or password. What makes id.wave.com unique is that it is the only service that ties identity to the device. Credentials are stored in a closed cryptographic security chip called a Trusted Platform Module or TPM, which allows the machine to be identified to the web account. Once a user logs into his or her PC, id.wave.com logs the user into participating websites, while passwords and encryption keys remain locked away in the TPM chip, safe from any software-based attacks.
