Hi Anthony,
I am getting an error “Cannot read property 'isFirstChange' of undefined
at MatPasswordStrengthComponent.ngOnChanges (angular-material-extensions-password-strength.js:454)” at page load . I debug it and find that “changes.password” is undefined . Please look it into image .

My suggestion is please replace code “if ((changes.externalError && changes.externalError.firstChange) || changes.password.isFirstChange()) {
return;
}” by “if ((changes.externalError && changes.externalError.firstChange) || changes.password && changes.password.isFirstChange()) {
return;
}” to fixed this bug.
