We’ve made two components like this at NoCode Monkey if anyone is interested.
1.) Input Validator: This is a button similar to the email validator. It will allow you to set minimum character limits, exclude different character, and set stronger restrictions with Regex. https://youtu.be/afzf7xw8N5E
2.) Better Sign Up Form: This one is the full package. Allows you to set password requirements at the click of a button. You can also hide/reveal the password to make sure you typed it correctly.
Here’s a video of the component in action.
