Hello.
I’m creating a closed committee site which requires “user name” and “password” to log in. However, URL of each user page displays their user name (e.g.: “site name”/”domain”/”directory”/”user name”) so that user may be at risk of brute force attack and hacking.
Please tell me how to change the permanent link of user page “user name” to “user id” or another one.
