Easy logins for Ruby web applications

Users hate picking and having to remember them. Developers hate dealing with and storing them. Why are we still using passwords again? Surely there is a better way to log into websites.

This talk will introduce the technology behind Persona and the BrowserID protocol. Mozilla intends to solve the password problem on the web with a federated cross-browser system that is intensely focused on user experience and privacy.

We may not be able to get rid of all passwords, after all, you probably don’t want to be subjected to a fingerprint check before leaving a comment on someone’s blog, but we can eliminate site-specific passwords and replace them with something better: a decentralized system that’s under the control of users, not a for-profit gatekeeper.

It’s just four easy steps to add it to your Ruby site/app from scratch and there are already plugins for Devise, Omniauth, Rails, Sinatra, and Warden.

19. passwords are hard to secure they are a liability
20. ALTER TABLE user DROP COLUMN password;
21. problem #2: passwords are hard to remember
22. pick an easy password
23. pick an easy password use it everywhere
24. passwords are hard to remember they need to be reset
26. control email account control all accounts =
28. “People want a little dating before marriage.” Eric Vishria – Rockmelt
30. decentralised
31. myid.com/u/francois
34. privacy ®
35. existing login systems are not good enough
36. ideal web-wide identity system
37. ideal web-wide identity system
38. ideal web-wide identity system
39. ideal web-wide identity system
40. what if it were a standard part of the web browser?
42. how does it work?
43. fmarier@gmail.com
44. fmarier@gmail.com
45. getting a proof of email ownership
46. authenticate?
47. authenticate? public key
48. authenticate? public key signed public key
49. you have a signed statement from your provider that you own your email address
51. logging into a 3rd party site
52. Valid for: 2 minutes wikipedia.org assertion
53. Valid for: 2 minutes wikipedia.org check audience assertion
54. Valid for: 2 minutes wikipedia.org check audience check expiry assertion
55. Valid for: 2 minutes wikipedia.org check audience check expiry check signature assertion
56. assertion Valid for: 2 minutes wikipedia.org public key
57. assertion Valid for: 2 minutes wikipedia.org
58. assertion session cookie
59. demo #1: http://www.voo.st/ http://www.debuggex.com fmariertest@eyedee.me
60. Persona is already a decentralised system
61. decentralisation is the answer, but it's not a product adoption strategy
62. we can't wait for all domains to adopt Persona
63. we can't wait for all domains to adopt Persona solution: a temporary centralised fallback
64. demo #2: http://sloblog.io/ fmariertest@aol.com
65. Persona already works with all email domains
66. identity bridging
67. demo #3: http://www.reasonwell.com/ fmariertest@yahoo.com
71. Persona supports all modern browsers >= 8
72. Persona is decentralised, simple and cross-browser
73. it's simple for users, but is it also simple for developers?
