Re^3: Breaking Out of the Perl Echo Chamber (OpenID)

but is there any particular advantage choosing one provider over another?

Most importantly you should trust your OpenID provider. He can track your logins to SO, and if he decides to go evil he can log with your ID (without you ever noticing), and if he stops to provide his services, you're locked out.

So if you equally trust both OpenID providers, I don't see why you should chose one over the other - just go with the one you like better.

I personally believe that I must be very dumb then! I think I've understood what OpenID is about and I've read extensively those other blog entries linked to here which explain its inherent risks. However, I decided to trust it: to be sure, I chose flickr as my provider, and I duly enabled OpenID support. Now I go to http://stackoverflow.com/users/authenticate and I select flickr as a provider, adding my ID there, which is -unsurprisingly- `blazar`. Then I click on the login button, and I'm brought to Yahoo!'s login page, where I do login. (Alternatively, I may have already been logged in, in which case this step would have been skipped: I tried many times already, logging in, logging out...) Now it tells me (in Italian, so maybe the words won't be just the same as those you'd see...) that "I'm entering stackoverflow.com" and to press "let me in" to do so. But when I do so, I'm brought back to SO, where they tell me that they couldn't authenticate me. And I've tried several times, on several PC's deleting cookies, and making all sort of attempts! So what's up with it? Update: what that's described above is the situation as it has been all of yesterday up to another attempt tried this morning. [Murphy's law?] I tried one more time after posting this, and... it works now! I presume it takes "some time" for this OpenID thingy to really "activate," doesn't it? `--` If you can't understand the incipit, then please check the IPB Campaign.	[reply] [d/l] [select]
