Final answer:
Logging in to a site does not necessarily mean the client is authorized to use it.
Step-by-step explanation:
If a client can log in to a site, it does not necessarily mean they are authorized to use it. Authorization refers to the permissions granted to a user after they have successfully logged in. Logging in simply means providing valid credentials to access the site, but authorization determines what actions the user can perform once they are logged in.
For example, a client may log in to a social media site, but they may only be authorized to view content and not post or comment. So, the statement is False.
