Is there a way to disable chrome autofill option for angular form fields

Question

I have tried using autocomplete false and also auto complete off. The cache is removed from the field, but iam still seeing chrome autofill data. Is there a way to disable chrome autofill option in angular forms? Any suggestions would be appreciated. Thanks

Answer 1

Please check the autocomplete="new-password":

<input type="password" name="password" value=""  autocomplete="new-password" />

It worked for me. Found in Google documentation

Answer 2

The autocomplete="off" is effectively respected by Chrome, but what you're experiencing is the Chrome autofill functionality that takes over, ignoring autocomplete="off": https://developers.google.com/web/updates/2015/06/checkout-faster-with-autofill.

In the past, many developers would add autocomplete="off" to their form fields to prevent the browser from performing any kind of autocomplete functionality. While Chrome will still respect this tag for autocomplete data, it will not respect it for autofill data.

One workaround is to put an unknown value in the autocomplete, e.g. <input type="text" name="somethingAutofillDoesntKnow" autocomplete="doNotAutoComplete" />. When testing this it worked for me most of the time, but for some reason didn't work anymore afterwards.

My advise is not to fight against it and use it's potential by properly using the autocomplete attribute as explained here: https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofill

Through some trial and error testing, it appears that if you set the input name and autocomplete attributes to a random string, Chrome's autofill is prevented from appearing. I created a small directive to achieve this.

import { Directive, ElementRef, Renderer2, AfterViewInit } from '@angular/core';

@Directive({
  selector: '[appDisableAutofill]'
})
export class DiableAutofillDirective implements AfterViewInit {

  constructor(private readonly el: ElementRef, private readonly renderer: Renderer2) { }

  ngAfterViewInit() {
    const randomString = Math.random().toString(36).slice(-6);
    this.renderer.setAttribute(this.el.nativeElement, 'name', randomString);
    this.renderer.setAttribute(this.el.nativeElement, 'autocomplete', randomString);
  }

}

Just change your input from type TEXT to type SEARCH.

<input type="search" name="your_address" autocomplete="nope" />

Chrome fill work with text fields but it's ignored on search type.

Chrome seems to ignore all practical/clean attempts to stop this - so we need to get a little hacky. I prevented this using 2 honeypot inputs. They can NOT be "display:none" or they will get skipped. So I wrapped them in a div that's height:0; overflow:hidden; and gave them opacity 0 (just to be double sure). Your real inputs must come AFTER the honeypots. See below

<!-- honeypot prevents chrome user autofill bs-->
<div style="height:0; overflow:hidden">
    <input style="opacity:0;" type="email" value="" class="" />
    <input style="opacity:0;" type="password" value=""  class="d-" />
</div>
<!-- end honeypot -->

<!-- ... then put your real inputs after-->
<input type="email" name="email" value="" class="" />
<input type="password" name="password" value=""  class="d-" />
<!-- end honeypot -->

Disabling autocompletion

To disable autocompletion in forms, you can set the autocomplete attribute to "off": You can do this either for an entire form, or for specific input elements in a form:

<form [formGroup]="exampleForm" autocomplete="off">
 ...
</form>
// or
<form [formGroup]="exampleForm">
 <div>
  <label >Credit card:</label>
  <input type="text" id="cc" name="cc" autocomplete="off">
 </div>
</form>

To Disable in Login Fields: many modern browsers do not support autocomplete="off" for login fields:

to prevent autofilling of password fields, you can use

autocomplete="new-password"

I had similar issue, I was not able to resolved it with any of the solution maybe because I was using third party for Google places Autocomplete ngx-google-places-autocomplete where autofill overlapping google suggested address. I was able to resolve it using focus event as shown below

<input ngx-google-places-autocomplete [options]='options' #placesRef="ngx-places" (onAddressChange)="handleAddressChange($event)"
      type="text" class="form-control"  id="address1"
        formControlName="address1" placeholder="Street address, P.O. box" required (focus)="setAutoFillOff($event)">

  setAutoFillOff(event: any) {
    if (event) {
      event.target.attributes['autocomplete'].value = 'chrome-off';
    }
  }

I am putting out this to helps who might be in similar situation.

It appears that autocomplete="off" can be used directly on form tag. Useful when you have a lot of text inputs

<form [formGroup]="vmForm" autocomplete="off">

Answer 9

TLDR; Don't label your inputs with obvious names or Chrome will pick that up and autofill the input.

I often use a form-group class to wrap my labels and inputs together, pretty common practice. So much so the only way I found to get around AutoFill in Chrome (Angular 8, Chrome v80) was to change the value of my label for the input.

Turns Off AutoFill:

<div class="form-group">
  <label for="aRandomPlace" class="form-group-label">Pickup Location</label>
  <input type="text" name="aRandomPlace" [(ngModel)]="data.address" class="form-group-input">
</div>

Does Not Turn Off AutoFill:

<div class="form-group">
 <label for="address" class="form-group-label">Pickup Address</label>
 <input type="text" name="address" [(ngModel)]="data.address" class="form-group-input">
</div>

I believe we are discussing to disable 'autosuggestions' not 'autocomplete' "Autocomplete=off" works for the text type input field but the browser ignores it if it is password type. there are lot many suggestions to use "Autocomplete='chrome-off', 'new-password'" but these are not meant to disable autosuggestions.

for these, I prefer masking technique to mask the content.

.autocompleteOff{
   -webkit-text-security: disc;
}

<input class='autocompleteOff' type=text>

Answer 11

Just add to all the HTML input tag which is being auto filled within a form tag as bellow:

<input type="text" class="form-control" id="inputId"
               name="inputName" autocomplete="new-inputName"  
               [(ngModel)]="model">

Note: Use "new-form_element_name" as autocomplete property as shown above.

It worked for me!!!

Answer 12

Usually what I do is I change type of input dynamically for example in Angular:

[type]="(field.length > 0)? 'password' : 'text'"

In this manner, the browser is unable to recognise the password field the first time you click it and will not provide a suggestion. However, if the field value has been input once and then erased, the browser will provide a suggestion. (At least it is not providing suggestion for the first time).

Answer 13

Please check the autocomplete="off webauthn"

I came up with this method after reading the documentation https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofill

<input matInput type="password" formControlName="pwd" autocomplete="off webauthn">

Answer 14

I found the answer in documentation and it works like a charm. You can find more about it here.

    <input type="text" autocomplete="off" name="one-time-code" id="one-time-code">
