Users Duplicated

Hi,

Thank you for the plugin ??

I have a big problem. I have noticed the following behaviour using Google login:
1. Customer goes and registers to our Website using Google
2. Account is generated in WordPress
3. Customer logout
4. Customer login again using Google
5. A new account is created in WordPress even though he registered previously using the same email address.

So at the end customer has many accounts when he logout and he login.

Thank you!
Best Regards
