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!
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 ...
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 ...
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 ...
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 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..."
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.
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 "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 ...
To add Launchpad login to your account, you can click this multi user link (works for who ever clicks it) to go to your profile and then click on "add more logins"

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.
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).
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?)
Yes, it should.
However, you cannot use your Launchpad OAuth login on any site other than Ask Ubuntu. So you should also add either a StackExchange local login or a secondary login from, say, Google or Facebook, in order to authenticate to other sites (when cross-site cookies don't work or such).
You'll have to login to Google first as you have discovered and use your LastPass creds there, then use Google OAuth / OpenID auth to authenticate with SE.
Your LastPass credentials being put into the email and password boxes on the logon page for StackExchange / Ask Ubuntu would be for StackExchange created OpenIDs, if you had registered without using an ...
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 ...
I think you're confusing two things together:
(1) Email Settings
(2) Your Logins
Email Settings lets you set the preferred contact address. If you add additional email addresses to your logins and set StackExchange login passwords you'll have to delink those logins from your account separately.
If you mean the email preference information in Email ...
First, you need to gain access to your old account:
Then, you need to merge the old account with the new account:
Be sure to edit the new account to be "merge keep" and the old one to be "merge delete".
See https://meta.stackexchange.com/questions/222556/how-to-log-out-of-a-stack-exchange-site for the step-by-step video.
Look in the top bar, right-most icon ("A list of all 176 Stack Exchange Sites"). It's in there.
Login is really by OpenID (and similar methods, eg Google accounts, Facebook, etc) only. That said, StackExchange does have their own OpenID provider, if you don't already have one. So I would suggest:
Register for an Stack Exchange OpenID account,
Add https://openid.stackexchange.com to your logins,
Optionally then delete your Google account from your ...
