Persona is way to log in to many different websites using your email address.
Instead of remembering different usernames and passwords for each website you visit, Persona is a "single sign on" solution that gives you just one thing to remember -- your own email address.
iVocalize 6 uses Persona to authenticate users, so you have one account to access any room in our system, and no extra passwords to remember.
Persona has just released this video about their Beta 2 release.
