Incubator Password Strength for Flow

Incubator Password Strength for Flow is server-side component of incubator-password-strength web component for Vaadin 10. It provides a strength indicator for a password field.

Usage

Strength can be set from 0 to 5. Strength represent number of blocks that would be filled with color and color of fill ling(0 - nothing, 1 - red, 2 - orange, 3 - yellow, 4 - light green, 5 - dark green). Setting strength to more then 5 will make no difference from just setting it to 5.

PasswordStrength passwordStrength = new PasswordStrength();
passwordStrength.setStrength(4);

Setting strength to 4 mean will indicate good password strength.

Common use case would be to track changes of PasswordField and then calculating and setting strength on every change:

passwordField.addValueChangeListener(changeEvent -> {
    passwordStrength.setStrength(changeEvent.getValue().length() / 3);
});
