Question: Is it possible to use `www.website.com/username(cpanel)` instead of:

`www.website.com/cpanel`

To access the cpanel?

Please suggest an idea.

Answer: 
No this is not possible 

But you can set redirection which will redirect www.website.com/username to www.website.com:2082 to achieve your requirements
You cannot use your username because the username cannot be a keyword and if you have any file with same file name in your home directory, the chaos occurs. Hence, cPanel don't have the provision of the same.

```
http(s)://domainname.tld/cPanel

```

should be used.
