AppleID Not been accepted in XCode account pane I've notived my Apple ID is not been accepted within XCode when I try add an Apple ID in the XCode accounts pane of preferences.

I have tested the account details in both the member ceter and itunes connect sites and the account is fine.

When I add the account details and click 'Add' I get the message:

john@abcdef.com could not sign in. Please sign in with an app-specific password. You can create one at appleid.apple.com


Any ideas? I've updated XCode (7.2.1) and Yosemite (10.10.5), rebooted etc but same thing everytime.

Note: I have a second apple id which does NOT have a developer license, I use this for my ipad store purchases and this logs into XCode fine strangely.

Make sure the Apple ID you're using is registered as an Apple Developer, XCode does not function with normal Apple IDs since they aren't linked to Apple's developer tools.
