I'm pretty sure you used to be able to link your existing Stack Exchange profiles together, but I just had to sign up from scratch on a site (as well as this one), with some random username.

I'm already active on a couple of sites, using the same username. It wouldn't accept my Stack Exchange id when I tried, so I have no idea how to link them.

How do I do it?

Worse still, now this random id seems to have been linked with the other random id on the sci-fi site.

I just want my username back!

  • Try to log in with your user credentials, and the system should offer an fusion with your ID

  • It didn't. It told me I didn't exist, even though in the SAME browser I had a stackexchange tab open and logged in.

  • That's because your account didn't exist on that site. You have to create a new account, but you enter the credentials from your existing account. Nov 12 '13 at 12:48
  • But since you already have an account now, try adding your existing credentials... see if this helps Add new email to login credentials Nov 12 '13 at 12:48
  • I entered the credentials. It told me they were wrong. thanks, but I give up - this isn't worth the work.

  • It's not too late. You can still merge your accounts. Nov 12 '13 at 12:51
  • Did you try to add the login with the link? Failing that contact the SE team via the contact us link in the footer. Explain the situation and they will try to help. Nov 12 '13 at 12:51
  • @Sha doesn't he need both accounts on the same site to do a merge? Or are separate accounts on separate sites also considered a merge? Nov 12 '13 at 12:52
  • @psubsee2003 good point, didn't think of that! The OP here seem to have given up though, or succeeded in merge after all. :) Nov 12 '13 at 12:56

Go to your profile (meta.stackoverflow.com/users/241421/user19585) and them into, my logins link in the upper right side, and finally in add more logins

    This answer is very incomplete and really doesn't completely address the OP's problem. You should try to expand it to be a complete answer Nov 12 '13 at 12:59
