What steps can I take to disable autofill in form fields during the development of an Angular project?

As I develop a web application using Angular, I'm facing an issue with autofill in form fields. Testing my forms in Chrome reveals that the browser automatically populates some fields with saved information, hindering the testing process and inconveniencing users by suggesting incorrect data.

Despite trying to set the autocomplete attribute to "off" on my form fields, it appears to be unreliable. Are there more effective methods to prevent autofill in Angular? How can I ensure consistent prevention of autofill in Angular Reactive forms? Do any Angular-specific techniques or best practices exist for managing this problem? Any suggestions or insights are greatly appreciated. Thank you for your assistance!

To make each input field unique, simply add a different attribute name with a distinct value. For example, in the code snippet below, I have included name="firstname".

<mat-form-field>
  <mat-label>First Name:</mat-label>
  <input matInput name="firstname" autocomplete="off">
</mat-form-field>

Furthermore, if you need to use the same input field multiple times within your project, consider altering it slightly, such as using name="fname". Always strive to use unique field names to avoid repetition.

If you're utilizing Angular Reactive Forms, you have the ability to manage autofill behavior programmatically within your component's code. By resetting the form control values to empty strings after form initialization, you can effectively prevent autofill from interfering.

Here's a snippet of sample code to demonstrate:

import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup } from '@angular/forms';

@Component({
  selector: 'app-my-form',
  templateUrl: './my-form.component.html',
  styleUrls: ['./my-form.component.css']
})
export class MyFormComponent implements OnInit {
  myForm: FormGroup;

  constructor(private fb: FormBuilder) { }

  ngOnInit(): void {
    this.myForm = this.fb.group({
      // Define your form controls here
    });

    this.resetForm();
  }

  resetForm(): void {
    // Reset form controls to empty strings to prevent autofill
    this.myForm.reset();
  }
}
