  14. 14. Core idea - Standard public key cryptography ● User's device mints new key pair, gives public key to server ● Server asks user's device to sign data to verify the user. ● One device, many services, "bring your own device" enabled Based on Asymmetric Cryptography

  17. 17. Google’s Experience
  18. 18. ● Enterprise use case ○ Mandated for Google employees ○ Corporate SSO (Web) ○ SSH ○ Forms basis of all authentication ● Consumer use case ○ Available as opt-in for Google consumers ○ Adopted by other relying parties too: Dropbox, Github Deployment at Google
  19. 19. Use cases at Google ● Bootstrapping ○ Only used when an employee signs in on a new device the first time ○ This protects against phishing ○ Removable Security Key is carried as part of badge ● Hardware credential binding ○ Once I’ve signed in to a device, long lived tokens (cookies, etc) is usually issued ○ Every once in a while, a local security key touch is required which is presented in combination with this local token - this is done to ensure that the token is still presented from a machine we trust

  21. 21. Security Keys are faster to use than OTPs "If you've been reading your e-mail" takeaway: Time to authenticate
  22. 22. Second factor support incidents
  23. 23. Security Keys cause fewer support incidents than OTPs "If you've been reading your e-mail" takeaway: Second factor support incidents
  24. 24. We’re not quite done
  25. 25. Proprietary + Confidential Does this work with a mobile? How do we deploy this at scale? What if they lose their key? But what about other enterprises?
