Oh, I have been fantasizing about a similar thing for about a decade! Currently my "account manager" is either an e-mail folder (I save the welcome e-mails), or my Facebook/Google account (the "authorized apps" page), and this is far from ideal. I also wish I could sign up for new websites/services using such a manager. If it already had all my personal info, it would take just one click to sign up. And maybe selecting which personal details I would like to disclose with the website. Mozilla Persona with browser integration[1] was the closest thing to that. Too bad it was abandoned.
