I'm not hearing consensus to make any specific changes to this parameter.

FWIW, we ignore this parameter completely as our UI is adaptive to screen size already.

IMHO, the display parameter already feels obsolete (I mean fixed pixel recommendations and wap feature phones?) and the world would be a better place if Connect was just silent on it and let the AS apply whatever display optimization heuristics it has at its disposal, which will no doubt evolve over time.

Yes, this is a carry over from OpenID 2 and the popup window. I'm not sure a fixed size makes sense any more as each idp has its own dimensions. One of the original goals was to prevent window resizing but that is pretty much given in today's environment.

The main guidance I would give is that the popup window shouldn't cover more than X% of the screen. Hopefully some ui team will know what X is:)

For me, if the popup covers more than say 60% of the screen it's better to move the user to a full page redirect model. We've done this for most of our mobile and tablet flows because popups on mobile are a little weird UX wise.

Thanks,
George

I think it was from the UI extension for openID 2.   I remember that there was a reason Google and the other authors of that extension needed it a fixed size at the time.  Something about the RP popping the window and the IdP needing to know the size to display text properly.

Now that we assume browsers are JS capable (Not so true 5 years ago) the IdP can likely dynamically determine the size.  It might still be a good idea to recommend a hight x width ratio.

JainRain and others can probably say what the current best practice is.

Microsoft developers were asking where the 450x500 dimensions came from and if they're the right ones.  Who know the history of where these dimensions came from?

Many devices don't support 450 x 500 pixels

Rather than saying "The popup User-Agent window SHOULD be 450 pixels wide and 500 pixels tall" should we say "The popup User-Agent window SHOULD be a minimum of 450 pixels wide and 500 pixels tall"?

Yeah, no kidding. And what about on Retina displays?  This guidance seems in appropriate.

A question from developers that I forgot to ask on Monday:  Why is 450 x 500 the recommended window size for display=popup and is this the right size?
