How to connect two database of different wordpress sites?

Question

I am having two different sites based on wordpress. I want to give access to the users to both the sites even if they sign-up on any of one.

Example:

If user xyz sign-up for example1.com then user's data must be stored in both website's data-base example1.com and example2.com so user don't need to sign-up for example2.com if he has sign-up in example1.com and vice-versa.

So how can I connect this data-base with each other?

If user sign-up in example1.com then fields of data-base in wordpress having table wp_user by default should receive that information of user in both sites.

In short, I want to connect data-base of both sites having table wp_user.
