I couldn’t remember if I’d signed up with my Google or Twitter accounts. I tried Twitter first and that wasn’t it, so I then went and logged in with Google.
If we could assign multiple login providers to the same account it would be useful, especially when my Google login profile ‘links’ to my Twitter profile anyway.
You can link multiple social accounts. The easiest way is if they all present the same email address for you - the OneAll authenticator will detect that and match you up. Because we’re using an extended profile system, however, there’s not a way to declaratively link multiple social accounts right now. You can try (whilst logged in already) hitting Log In ‹ PowerShell.org — WordPress; if it lets you in, there’s a “Connect your account” section.
