Library's components

• <mat-password-strength> used to calculate and display the strength of a provided password

1. strength score <= 20%

2. strength score <= 80%

1. strength score > 80%

• <mat-password-strength-info> used to display more information about the strength of a provided password

• <mat-pass-toggle-visibility> used to show/hide the password provided in the input element

Dependencies

• Angular developed and tested with 12.x

Installation

1. Install via ng add. (Recommended)

If Angular Material Design is not setup, just run ng add @angular/material learn more

Now add the library via the angular schematics

ng add @angular-material-extensions/password-strength

2. Install via npm. (Alternative)

Now install @angular-material-extensions/password-strength via:

npm install --save @angular-material-extensions/password-strength

SystemJS

Note:If you are using SystemJS, you should adjust your configuration to point to the UMD bundle. In your systemjs config file, map needs to tell the System loader where to look for @angular-material-extensions/password-strength:

{
  '@angular-material-extensions/password-strength';: 'node_modules/@angular-material-extensions/password-strength/bundles/password-strength.umd.js',
}

-> follow the instructions here

Import the library

Once installed you need to import the main module:

import { MatPasswordStrengthModule } from "@angular-material-extensions/password-strength";

The only remaining part is to list the imported module in your application module. The exact method will be slightly different for the root (top-level) module for which you should end up with the code similar to (notice MatPasswordStrengthModule .forRoot()):

import { MatPasswordStrengthModule } from '@angular-material-extensions/password-strength';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [MatPasswordStrengthModule.forRoot(), ...],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Other modules in your application can simply import MatPasswordStrengthModule:

import { MatPasswordStrengthModule } from '@angular-material-extensions/password-strength';

@NgModule({
  declarations: [OtherComponent, ...],
  imports: [MatPasswordStrengthModule, ...],
})
export class OtherModule {
}

API

<mat-password-strength> used to calculate and display the strength of a provided password - see the demo examples

<mat-password-strength-info> used to display more information about the strength of a provided password - see the demo examples

<mat-pass-toggle-visibility> used to show/hide the password provided in the input element

Usage

add the @angular-material-extensions/password-strength element to your template:

<mat-password-strength [password]="password.value"> </mat-password-strength>

This will display only the material password strength meter in form of a progress without any input fields or similar.

In the following example, we integration a material input container with @angular-material-extensions/password-strength 's component.

NOTE: In order to repaint the mat-form-field correctly after changing the value of the password's strength, please consider to change the detection strategy for the parent component -->

import {
  ChangeDetectionStrategy,
  Component,
  OnInit,
  ViewEncapsulation,
} from "@angular/core";
import { Title } from "@angular/platform-browser";
import { MatSlideToggleChange } from "@angular/material";
import { MatPasswordStrengthComponent } from "@angular-material-extensions/password-strength";

@Component({
  selector: "app-home",
  templateUrl: "./home.component.html",
  styleUrls: ["./home.component.scss"],
  encapsulation: ViewEncapsulation.None,
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export class HomeComponent implements OnInit {}

<div>
  <mat-form-field
    appearance="outline"
    style="width: 100%"
    [color]="passwordComponent.color"
  >
    <mat-label>Password</mat-label>
    <input
      matInput
      #password
      [type]="inputType"
      required
      placeholder="Password"
    />
    <mat-hint align="end" aria-live="polite">
      {{password.value.length}} / 25
    </mat-hint>
  </mat-form-field>

  <mat-password-strength
    #passwordComponent
    (onStrengthChanged)="onStrengthChanged($event)"
    [password]="password.value"
  >
  </mat-password-strength>
</div>

Example of how to use the emitted strength of the password in your template

<div fxLayout="row" fxLayoutGap="10px">
  <div *ngIf="passwordComponent.strength === 100; then done else error"></div>
  <ng-template #done>
    <mat-icon color="primary">done</mat-icon>
  </ng-template>
  <ng-template #error>
    <mat-icon color="warn">error</mat-icon>
  </ng-template>
  <div>
    <p>Password's strength = {{passwordComponent.strength}} %100</p>
  </div>
</div>

Use the toggle visibility component

• add the mat-pass-toggle-visibility to your mat-form-field
• give it a name to use it in the html file like toggle
• set the type of the input to that value emitted from the mat-pass-toggle-visibility component <input matInput [type]="toggle.type"/>

<mat-form-field
  appearance="outline"
  style="width: 100%"
  [color]="passwordComponent.color"
>
  <mat-label>Password</mat-label>
  <!-- HERE DOWN :D-->
  <mat-pass-toggle-visibility #toggle matSuffix></mat-pass-toggle-visibility>
  <!-- THERE ABOVE ;)-->
  <input
    matInput
    #password
    [type]="toggle.type"
    required
    placeholder="Password"
  />
  <mat-hint align="end" aria-live="polite">
    {{password.value.length}} / 25
  </mat-hint>
</mat-form-field>

Client Side password's validation using a built in angular formController

1. add an input element to your template with an appropriate @angular-material-extensions/password-strength's component
2. hold a reference of the @angular-material-extensions/password-strength's component by adding passwordComponentWithValidation (or whatever you want) inside the element

e.g:

<mat-password-strength
  #passwordComponentWithValidation
  [password]="passwordWithValidation.value"
>
</mat-password-strength>

3. bind the form controller of the mat-password-strength to the input element

• you can access the form controller of @angular-material-extensions/password-strength using the chile view --> passwordComponentWithValidation.passwordFormControl
• bind the form controller to an input element --> [formControl]="passwordComponentWithValidation.passwordFormControl"

4. Full example - see below

<div>
  <mat-form-field appearance="outline" style="width: 100%">
    <mat-label>Password</mat-label>
    <input
      matInput
      #passwordWithValidation
      [type]="inputType"
      required
      [formControl]="passwordComponentWithValidation.passwordFormControl"
      placeholder="Password"
    />
    <mat-hint align="end" aria-live="polite">
      {{passwordWithValidation.value.length}} / 25
    </mat-hint>
    <mat-error
      *ngIf="passwordComponentWithValidation.passwordFormControl.hasError('required')"
    >
      Password is required
    </mat-error>
    <mat-error
      *ngIf="passwordComponentWithValidation.passwordFormControl.hasError('pattern')"
    >
      Password is not valid
    </mat-error>
  </mat-form-field>
  <mat-password-strength
    #passwordComponentWithValidation
    (onStrengthChanged)="onStrengthChanged($event)"
    [password]="passwordWithValidation.value"
  >
  </mat-password-strength>
  <!--Password's strength info-->
  <mat-password-strength-info
    [passwordComponent]="passwordComponentWithValidation"
  >
  </mat-password-strength-info>
</div>

this will looks like -->

custom regex validation

please consider to use the customValidator input (see below)

<mat-slide-toggle #toggle>Show Password Details</mat-slide-toggle>

<mat-form-field
  appearance="outline"
  style="width: 100%"
  [color]="passwordComponent.color"
>
  <mat-label>Password</mat-label>
  <mat-pass-toggle-visibility
    #toggleVisbility
    matSuffix
  ></mat-pass-toggle-visibility>
  <input
    matInput
    #password
    [type]="toggleVisbility.type"
    placeholder="Password"
  />
  <mat-hint align="end" aria-live="polite">
    {{password.value.length}} / {{passwordComponent.max}}
  </mat-hint>
</mat-form-field>

<mat-password-strength
  #passwordComponent
  (onStrengthChanged)="onStrengthChanged($event)"
  [password]="password.value"
  [customValidator]="pattern"
>
</mat-password-strength>

<mat-password-strength-info
  *ngIf="toggle.checked"
  [passwordComponent]="passwordComponent6"
  customCharsCriteriaMsg="1 german special chars is required"
  [enableScoreInfo]="true"
>
</mat-password-strength-info>

pattern = new RegExp(/^(?=.*?[äöüÄÖÜß])/);

Confirm the password with built in angular form controllers - see the live example

Use always the green color for a strong password just by adding the green css class to the mat-password-strength

<mat-password-strength
  #passwordComponent
  class="green"
  [password]="password.value"
>
</mat-password-strength>
