Not a bug Facebook Issue

[kkm323]

When user sign up via facebook , then disassociate their Facebook account. They can't use the site. I try using my Facebook's password and its shows this message "Incorrect password. Please try again".

Edit: You can reset your password though , but I think the user have to be alert before disassociate their Facebook account

Check your spam account.

Right under the button to disassociate facebook it says: Disassociating with Facebook will cause a password to be generated for your account and emailed to youremail@provider.com.
