and also a regex for password that matches
alphanumeric have at least one digit and one character

^ means beginning of line\S means all characters but not a space or a tab+ mean at least one character\w means an alphanumeric character including _{8,32} means at least 8 characters, and max 32\S still means all characters but not a space or a tab{1,} means at least 1 item
