Hello @Bmuzammil, Welcome.

From a security point of view, there is nothing wrong with spaces.
A problem arises only during processing, because there is not only one space character. In addition to the standard (U+0020), others are common, especially in word processing (U+00A0, U+2007, U+2008).

There is also a problem if you work in a shell and have to pass the space as part of a password or path. Then you have to enter e.g. '%20' or '\ ' instead of ' '.

For these reasons many manufacturers (hardware and software) do not allow blanks.
