cPanel Account Password - Query

Hi,

I would like to know if it is possible to disable specific special character when creating cPanel account?
I want to disable "@" character. I do have an Auto Installer Script (Softaculous) which uses User Authentication via the URL itself.

For Example:

If my user is: billyboxer and password is: b@xer111, then the URL will look like this:
/https://billyboxer:b@xer111@my.domain.com:2083/frontend/x3/softaculous/index.live.php

Usually, this won't work because my password contains "@" character. The URL won't recognized the domain address and will give me this kind of error.

Code:

getaddrinfo(3) failed for xer111@my.domain.com:2083
Couldn't resolve host 'xer111@my.domain.com'

Please advise.

Thank You.
