Yes you can. The whole network of StackExchange sites supports OpenID logins and since Launchpad provides OpenID login facility, you can use it to register an account here.
After following the Login link, you have the possibility to select an Open ID provider. Launchpad is one of them. Simply press the Launchpad button, enter your Launchpad username and hit ...
The Launchpad login system in use here on Ask Ubuntu is 100% the OAuth mechanism.
The Launchpad OpenID login mechanism has been fully retired here on the Stack Exchange network; the OAuth mechanism, however, only works if you login to Ask Ubuntu first, and then elsewhere on the network, as it is not enabled for any other sites on the SE network.
(And I ...
Sorry about this, I made some breaking changes to the page to fix an issue on mobile but forgot to make sure it still worked on desktop!
This is fixed as of the next build which should happen sometime in the next few hours. Thanks for the report!
I, for one, like that the focus is not on registering before you can use askubuntu. There are pleny of websites/forums that force me to register only to show me a site that is not worth looking at for longer than 10 seconds.
I would be more happy if the login would work on my PS3 though.
I can confirm the behaviour but it isn't terminal.
If you click the "More sign up options" link and then click the "Sign up using Launchpad" link, you'll get a textbox that will pre-populate the OpenID box for you and will forward you onto Launchpad.
It's definitely a problem though. I'll punt this off to SE directly.
Update: It's been handed from SE mods ...
Ubuntu One uses the Ubuntu Single Sign On service, which acts as an OpenID Provider.
Stack Exchange supports OpenID login, so you can add this identity to your account:
Go to your profile page and click the my logins link near the top.
In the window that opens, pick add more logins...
On this page, enter https://login.ubuntu.com into the field for your ...
The way to get the link is:
Select your username (the avatar in the new not-technically black bar)
Click "My Logins"
Click "Add more logins..."
You should make sure that it is not because of insufficient reputation. You need 15 reputation to vote, and you get rep when someone upvotes your question or answer. Go and answer some questions, get some upvotes, then you should be able to up and down-vote for yourself.
The "secret" to changing accounts on computers is that Firefox has a master password + sync feature that enables syncing website passwords across all your devices with the website passwords protected by the Firefox master password.
To sync Firefox Quantum versions 57 and later follow these steps:
Login to Firefox with your master password.
Click the 3-bar ...
The email preference that you edited is not the login information that is being used to log in, but the main contact email that Stack Exchange would use to contact you (newsletters, notification digests, etc).
If you want to modify your previous login method, you need to remove it from Profile > Edit Profile & Settings > My Logins instead of Edit Email ...
There are several other ways to log into your account without using the SE OpenID service. We support Google (including Google's two-factor authentication), Facebook, Yahoo, and any other site that acts as an OpenID provider. You can use any combination of these credentials without any loss in functionality.
The reason for the password requirements was ...

The answer to Can I (and How do I) use my askubuntu account on other Stack Exchange sites? is actually still correct, but Stack Exchange has changed their login page some so it isn't quite clear.
On the login page you need to click "more login options" and then input your launchpad URL in the OpenID field.
It seems you cannot just change your log in, I guess one must be active at all times, I don't really know why.
You can however add more here, by clicking the add more logins button, then from the same page you can remove the previous one if you wish.
If for some reason, this still does not work, you can contact the SE team here.
For what it is worth, it should be possible to deduce the Ubuntu SSO identity URL from a Launchpad profile page.
Taking my own Launchpad profile page as an example, I can grab the OpenID discovery information about it:
$ curl -H 'Accept: application/xrds+xml' https://launchpad.net/~jamesh
Here's how I finally got in to my account:
Clear the cache and cookies in your browser. Then go to the login page and click the more OpenID options link. Put in https://launchpad.net/~<your-launchpad-user-name> and click sign in.
The next build will fix this.
An oversight on my part. None of our default* top-level providers require entering a name so I assumed the "More" div would always be expanded, my apologies.
*OpenID.SE, Google, Yahoo, MyOpenID, and Facebook
Due to the amount of spam we were getting the SE team has enabled required registration to ask a question. This does not, however, affect answers.
(It's actually been enabled for a bit now, a month and a half I think?)
It's still technically underneath the "logo" for StackExchange... but it's changed location and how the actual button looks like... it's at the right of the top bar, underneath a chat bubble-looking item that is meant to be the StackExchange logo, as shown in the screenshot below (freehand circles and arrows included for somewhat obvious reasons).
Just wanted to chime in as a long term user and "answerer".
The problem you're describing isn't new but I don't think it's a significant problem... And even if it were, restricting input doesn't fix the retention issues.
A barrier to entry just means fewer entries. That we can have anonymous contributors is one of the major Stack Exchange features. It ...
None of your points are fixed by requiring registration.
No more brain racking each time [an anonymous user suggests an edit] that adds substantially more information to a question. (Remember: Ubuntu can be boot in a live session, if the user reboots its system the cookie it's lost forever)
This is not a HUGE problem, it's something that occurs ...
