I've read about what charachers should usernames use, in linux, here: https://serverfault.com/a/578264/330936 but I would like to know if is there any problem if I will use the at sign "@" in my usernames. I will use it especially for my ftp accounts (I have a simple webserver with CentOS 7).
I don't want to be portable to other older versions of linux, nor other distros (maybe debian).
Is there any problem in using @
in usernames?
@domain.com
is not really part of the user name per se but an indication were to look this user up. – Sven♦ Oct 20 '17 at 8:40@domain
is not part of the username itself, but an indication where to look the username up/which domain it belongs to. This is one of the reasons why having an@
as part of the actual username is such a bad idea. – Sven♦ Oct 20 '17 at 9:12
