Angular Pwned Password Checker Directive
Protect your users from re-using a password known to be hacked with this simple Angular directive. Check out the example page to see how it works. The passwords never leave the browser memory and are not transmitted over the network.
Getting Started
If you just want to use the library to verify the passwords given by your users, follow the following 4 simple steps. For contributing, or building the library locally, see the section on building the library.
Supported Angular Versions | Angular Version | Password Checker Version | | ---------------- | ------------------------- | | 6.x | 1.0.0 | | 7.x | 2.2.0 | | 8.x | 3.0.0 | | 9.x | 4.0.0 | | 10.x | 5.0.0 | | 11.x | 6.0.0 | | 12.x | 7.0.0 | | 13.x | 8.0.1 | | 14.x | 9.0.0 | | 15.x | 10.0.0 | | 16.x | 11.0.0 | | 17.x | 12.0.0 | | 18.x | 13.0.0 |
Step 1: Install
Install the npm package.
npm i @triangular/password-checker
Step 2: Add to NgModule Imports
Then, add the PasswordCheckerModule to the imports of your app.
If you're using standalone components, you can skip this step.
import { NgModule } from '@angular/core';
import { PasswordCheckerModule } from '@triangular/password-checker';
@NgModule({
declarations: [
],
imports: [
PasswordCheckerModule,
],
providers: [],
bootstrap: [],
})
export class AppModule { }
Step 3: Add Directive to an Input
Now you can use the provided directive pwnedPasswordValidator on your reactive forms, to trigger the validation with the pwned password database whenever the form is being validated.
<input
pwnedPasswordValidator
formControlName="password"
type="password"
>
You can configure the directive by providing additional input bindings. Currently the API endpoint, the input debounce time, as well as the minimum occurrence of a password to fail the validation are configurable:
<input
pwnedPasswordValidator
pwnedPasswordMinimumOccurrenceForError="1"
pwnedPasswordApi="https://api.pwnedpasswords.com/range/"
pwnedPasswordApiCallDebounceTime="400"
formControlName="password"
type="password"
>
Alternatively, you can configure your module by using the PasswordCheckerModule.forRoot()
method.
@NgModule({
declarations: [
AppComponent,
ExampleComponent,
],
imports: [
BrowserModule,
FormsModule,
ReactiveFormsModule,
PasswordCheckerModule.forRoot( {
pwnedPasswordApiCallDebounceTime: 1000,
pwnedPasswordMinimumOccurrenceForError: 4,
pwnedPasswordApi: 'https://api.pwnedpasswords.com/range/',
}),
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Step 4: Provide Feedback
Don't forget to provide some feedback to your users:
<div
*ngIf="!form.get('password').pending && form.get('password').errors && form.get('password').errors.pwnedPasswordOccurrence"
class="invalid-feedback">
<h2>This password has been seen
<span class="invalid-feedback--highlight">
{{form.get('password').errors.pwnedPasswordOccurrence | number:'1.0-0' }}
</span>
times before</h2>
<p>This password has previously appeared in a data breach and should never be used.
If you've ever used it anywhere before, change it!
</p>
</div>
Building
As a pre-requisite to build the library, you need to install all the dependencies via npm install
or yarn
.
Building the Library
Before the sample app can be run, you need to build the library itself.
npm run ng -- build password-checker-lib --progress=false
Building the Sample App
After building the library, it is either possible to build the sample app, via
npm run ng -- build example-app --prod --progress=false
,or to run the sample app with a local dev server:
npm run ng -- serve
Running the tests
Unit Tests
There are not many tests, but those that are can be run with:
npm run test -- --no-watch --progress=false --code-coverage --browsers ChromeHeadless
And coding style tests
The project follows the angular style guide and lints with the following command:
npm run lint
