decentralisation is the answer, but it's not

a product adoption strategy

we can't wait for all browsersto adopt Persona

navigator.id.*

we can't wait for all browsersto adopt Persona

solution: a temporaryjavascript shim

LIFD

LocallyIsolatedFeatureDomain

goal: trusted coderunning in the browser

login.persona.org

localStorage

localStorage.setItem("key", serializedKey);

var serializedKey = localStorage.getItem("key");

storage tied tologin.persona.org

window.postMessage()

https://login.persona.org

Persona supportsall modern browsers

>= 8

demo #2:

Persona already workswith all email domains

identity bridging

demo #3:

Persona works everywhere

lessons learned

#1 user testingis critical

#2 nobody wantsto be first

“how many usersdoes Persona have?”

700,000,000

#3 if a problem hasbeen around for awhile, it's probablya hard one

see if you can solvepart of the problem
