Are there plans to implement the Mozilla Persona login system?

(imho) The Mozilla team are clearly a great presence on the web and the technologies that they look after are of great worth and have great motive.

It might make sense to consider supporting Persona logins on Stack Exchange sites.

Remember when OpenID was supposed to make things easier by consolidating everything into a single login that could be used everywhere? Doesn't the proliferation of OpenID providers kind of work against that theory? – Cody Gray Jul 27 '11 at 7:43
@Code Gray, Yes in general, but the interference of social network and their use of that info for marketing maybe is unwanted behavior. Another thing, Mozilla has been always the org which make the Internet more unified/standardized and a better place for everyone. – Kenan Deen Jul 27 '11 at 7:54

Perhaps in future, if Mozilla BrowserID is successful – Thursagen Jul 27 '11 at 8:11
@Cody, this is a courtesy notification for your reply above. – Pops Jul 27 '11 at 18:46
Anticipating everyone's first question: How does Persona compare to OpenID? TL;DR: Same goal, but avoids extra username and doesn't allow ID provider to track users. – blahdiblah Sep 28 '12 at 1:32
and can/will eventually be implemented by your browser... – davidsleeps Sep 28 '12 at 2:53
It's beta right now, right? – AakashM Sep 28 '12 at 7:45
@aakashm Think so, doesn't stop the planning of supporting it though – davidsleeps Sep 28 '12 at 8:13
I will second this, I like Persona much more than OpenID, and it takes a minute to implement. – Stavros Korokithakis Oct 21 '12 at 14:57
I use Persona on a multitude of sites and it works really well. I personally don't like OpenID so Persona offers a good alternative. Stack Overflow is actually on Mozilla's list of sites they would like to see using Persona too! – James Jan 8 '13 at 15:21
@jamescallumyoung is that documented somewhere (blog post, web page...)? – davidsleeps Jan 8 '13 at 21:05

We support OpenID logins because it is a widely adopted standard with a significant number of providers.

We support Facebook logins via OAuth2.0 (but did not via Facebook Connect), as OAuth2.0 is more or less a standard with a large number of users behind it. If/When Twitter supports OAuth2.0, we'll probably support it as well.

BrowserID isn't nearly prevalent enough to warrant consideration at this point.

But if a major service like Stack Exchange supported BrowserID, then other developers would be more likely to support it. – Chris Peterson Dec 17 '11 at 0:33
Firefox is going to support it natively soon (Firefox 17?). MDN uses it (and many other Mozilla sites). Can this be reconsidered? – Inkbug Aug 15 '12 at 16:50
The available four options for SO logins all share the same flow: they compromise your privacy. There is an open standard with a high state of polish that seems perfect for the extremely tech-literate community that is SO/SE. Why not be an early-ish adopter on this given the low cost to do so? – Ari B. Friedman Apr 9 '13 at 22:53
I have to agree with Ari here. User privacy is an issue that us developers need to stand up for. Persona has it, OpenID doesn't and can't. Combine that with the fact that Persona uses email addresses which means that regular users will be able to understand it far better than they ever will understand OpenID, and the fact that it can be implemented entirely in-browser without server support should be good reasons for Stack Overflow to stick its neck out and provide some support. The PR benefit alone should be worth it. – dasil003 Apr 24 '13 at 0:58
SE would be the perfect site to support Persona and make it more prevalent. Why wait for another site to make it prevalent when SE could lead the way. Persona is new, but it's also the best sign-in method yet. OpenID is ok, Persona is much better. – devlop Jun 24 '13 at 13:26
SE showed leadership in OpenID, but now that MyOpenID is going away (while still being promoted by SE), there ought to be an alternative. I suspect people picked MyOpenID to avoid using a Facebook/Google/Twitter login. I'm not sure if Personas, IndieAuth, or anything else is likely to get any traction without SE showing leadership again. – brianary Dec 28 '13 at 5:59
With MyOpenID going away in Feb. 2014, won't that affect OpenID usage significantly? Side note: I trust SE and Mozilla, so it's a win-win either way. I do not trust Google, Facebook, Yahoo (or AOL, LiveJournal, Wordpress, etc). – Kevin Suttle Jan 2 '14 at 21:19
@KevinSuttle not really. The vast vast majority of users use OpenID via Google, the rest are mostly our provider (also OpenID), and Facebook (OAuth 2.0). – Kevin Montrose Jan 2 '14 at 21:21
Persona now supports identity bridging to at least Yahoo and Google. From the following article "Persona now natively supports more than 700,000,000 active email users." What is your criteria for enough users for it to be worth it for SO? -… – Ben Kelly Jan 17 '14 at 4:15
I would also like to vote for supporting Persona. It's a great standard, both from a privacy and a usability standpoint, and SE supporting it would be helping it succeed. It is very, very easy to implement, so please at least consider it. – Stavros Korokithakis Feb 8 '14 at 1:26

What is the value of supporting Mozilla BrowserID?

About the same as CardSpace support would have been when MS launched that (with IE7 if I recall correctly).

Many have launched new authentication protocols and systems. Most have failed.

lol, CardSpace. – BoltClock's a Unicorn Jul 27 '11 at 8:23
@Tshepang Are you equating the two services in design or just their adoption rates? I ask because they are trying to solve the same problem with very different approaches and I don't just mean protocol but with a different user expectation and workflow. Here is my plug. Like it or not email is the most widely accepted, yet unofficial, identification mechanism. Mozilla is simply using Persona to make it official. As a user I may not have an MSDN, Facebook or Google account but I will most certainly have an email. Not a Mozilla email or a google email etc.. Any email I provide. – Ivan Apr 27 '14 at 4:10
@Ivan that should have been directed to Richard – Tshepang Apr 30 '14 at 8:39
@Ivan: Adoption success. About the only authentication mechanism showing any substantive support is OAuth (ie. using Twitter/Facebook/… login on other sites). Maybe Mozilla's will be successful, but in the almost three years since I wrote this answer I have yet to see it used anywhere (this could be the sites I visit, or it could be adoption rate, Occam's Razor says the latter). – Richard Apr 30 '14 at 8:50
