The discussion revolves around the absence of Single Sign-On (SSO) options on the mobile registration page. Jagster initially reported this issue, stating that only username/password options are available on mobile, whereas iPad displays all options. Chapoi explained that the SSO buttons were omitted to save space on mobile, with the assumption that users would first pass through the login modal, which does have SSO options. However, Jagster argued that this reasoning is flawed, as users may not understand SSO and are likely to use the create account option, only to find minimalistic username/password fields.
Chapoi acknowledged the issue and promised to look into adding SSO options to the current mobile registration page. JammyDodger expressed support for this change, and Chapoi later announced that the SSO options are now available in the create account modal on mobile, as of a recent GitHub pull request.
When a new user chooses to registrate there isn’t any SSO options (like Google etc.) available. Just plain old username/password.
iPad shows every options as should.
I don’t know when this broke up.
And I have recently updated version because I rebuilded this morning UTC.
I count this as a bug, but perhaps it is just another UX issue 
Hi,
Yes, that is a bit odd, I’ll try to frame that decision a little bit:
Because the create account form is already quite long on mobile, the idea was to save some space by omitting the SSO buttons. This sounds super strange, but the reasoning was that on mobile, you have to pass by the “login” modal first – which does have the SSO buttons and those can also be used to create your account, because logging in or signing up via SSO is basically the same action.
Of course that’s quite obscure knowledge and not very intuitive.
So I agree it would be better if they are shown on create account again. In the coming fullscreen login this will be fixed for sure.
In the meantime, I’ll take a look if we can squeeze them in the current one too.
That reasoning doesn’t work because an ordinary user doesn’t understanding what SSO even means.
Only what a new user sees is option to create new account and they use that. And gets very minimalistic page asking username and password.
Saving space is as bad reasoning, because login page isn’t any more fuller. First we should show SSO options and below those buttons old school way. Scrolling is not a new thing for users. We are still living in the world were janes ja joes are using google search of browser instead of giving url.
There you go @Jagster, I fixed your post for you. 
Touché 
That’s right. I should be less reactive, sometimes anyway.
The SSO options are as of UX: show the SSO options when creating an account on mobile by chapoi · Pull Request #25260 · discourse/discourse · GitHub available in the create account modal on mobile too.
