Appreciate you creating this addon! I wrote a library called Nbvcxz (https://github.com/GoSimpleLLC/nbvcxz) that was heavily inspired by zxcvbn in Java to do this type of validation server side. How hard was it to make this an addon?
Thanks! Server-side validation is usually more secure and easier to implement, but causes some latency for the user when updating the status after every keypress.
