I'm hosted in on una cloud-4 and I can't get to any of that. Is this something you can change for me?
I would just like only alphanumeric A-Z a-z 0-9 no symbols
We can change it for you, since it's very minor modification, but it's better to ask your users to change autogenerated password to their own.
Also why you want to change autogenerated password to be alphanumeric only ?
This is why :D
