A Vue.js Password input Component that includes a toggle to Show the password



VuePassword 3.x removes support for the zxcvbn library. The library appears to no longer be maintained. If you would still like to use it, you can still pull in the library and pass the VuePassword value to it to calculate the strength. Examples coming soon.


Install

Install the package using npm.

npm install --save vue-password

The VuePassword component adds support for a toggle to hide and show the password as well as a meter to show the current strength of the password. This component does not automatically calculate the strength, however, a library like zxcvbn can be used to pass the strength values as props.

import VuePassword from 'vue-password';

export default {
    ...
    components: {
        VuePassword,
    },
    ...
};


Usage

Use the props in your HTML and apply a v-model attribute for the password and any additional props for the desired configuration. The password input uses the $attrs attributes, so form validation props such as required, minlength, and maxlength will function on the input element. The following example shows how vue-password could be used in a registration form using Tailwind CSS.


Javascript

import Vue from 'vue'
import VuePassword from 'vue-password'

new Vue({
  el: '#app',
  components: {
    VuePassword
  },
  data {
    user: {
      email: '',
      password: ''
    }
  }
})


HTML

<form>
    <div class="mb-4">
        <label for="password">Password</label>
        <VuePassword
            v-model="password1"
            id="password1"
            :strength="strength"
            type="text"
        />
    </div>
</form>


Props

Use the following props to configure the password input.


Events

The password input emits an input event to use with v-model. Other events are binded use v-on="listeners".


Slots

Named slots can be used to change the layout of the password toggle, strength meter, and strength messages.
