I have created 3 website "A1", "A2", "A3" and all opening website from subfolder URL wise. for example main website url as http://example.com/ then when customer select "A1" website open url as http://example.com/A1/ etc.
Now My question is : Is it possible I will provide customer to access login for "A1" and "A3" website but not access "A2" website. similarly other customer come and we restrict to access "A1" & "A2" website but not "A3" website to login.
How to restrict customer to login by multiple website wise but not all website login.
