Disallow Users From Using Spaces and Special Characters in their Username

Hi there, @hascaleb… here are a couple of threads that might help.

Restrict special characters and spaces from input

There seems to be a couple of threads in the forum related to the subject but both seem rather old and I’m enquiring if anybody might have a more updated view. This relates to restricting characters on a text “input” which would exclude special characters and spaces. I can use filtering or regex and even conditions but from a UX perspective I was hoping to find a way to restrict the user entering those characters.

How do you limit special characters in the input field for usernames?

I basically want to restrict users from entering in the input field for usernames so question marks, commas, number signs, spaces, etc, are used for the username. Strictly only letters and numbers. Thanks in advance!

Best…
Mike
