Instead of having to go through my openID (Google, etc) providers authorization page every time I want to create a new account on foo.stackexchange.com; would it be possible to instead grant *.stackexchange.com authorization to use my openID and remove the step entirely?
- Visit new SE site for first time.
- Click login link on top of page.
- Click login with my openID providers button.
- Be directed to my openID providers authorization page.
- On openID providers page, click allow (or equivalent).
- Be returned to foo.SE.com and be prompted to link my newly created account with my other SE accounts.
If it was possible to authorize *.stackexchange.com on my openID once, steps 3-5 could be removed provided I was already logged into an existing SE site.
If openID won't provide an ID that can explicitly be used across subdomains, would it be possible to move all the openID logic to a single subdomain (authentication/logon.stackrxchange.com?) and have it share the data out across all the stack exchange sites? I realize this would require users to approve the new subdomain with their openID provider; but this would be a one-off update after which the streamlined process would be possible.
