  • Passwords will contain at least 1 upper case letter
  • Passwords will contain at least 1 lower case letter
  • Passwords will contain at least 1 number or special character
  • There is no length validation (min, max) in this regex!

Regular expression for JavaScript:

/((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/

One minor recommendation is to use

/(?:(?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/

https://regexper.com/#%2F%28%3F%3A%28%3F%3D.*%5Cd%29%7C%28%3F%3D.*%5CW%2B%29%29%28%3F!%5B.%5Cn%5D%29%28%3F%3D.*%5BA-Z%5D%29%28%3F%3D.*%5Ba-z%5D%29.*%24%2F

The ?: at the start of the first group tells the regexp engine not to capture the matches which will make it ever so slightly more performant.
