# Autofill forms on a site
Autofill in Yandex Browser enables users to quickly and safely enter [bank card numbers](https://yandex.com/support/browser/security/card-protection.html), [passwords](https://yandex.com/support/browser/security/passwords-management.html), and other personal data (such as contacts information) in forms. This can make it easier to place orders, encouraging users to order more often. Yandex research and experiments to improve autofill in order forms have shown that the conversion of orders is 5–10% higher on sites where this function works correctly.
For details, see [Autofill forms](https://browser.yandex.ru/help/personal-data-protection/autofill.html).
{% note info %}
If autofill doesn't work in Yandex Browser, it probably won't work in other browsers either.
{% endnote %}
To check autofill on a site:
## Step 1. Complete your profile in Yandex Browser {#full}
1. [Install Yandex Browser](https://yandex.com/support/browser/about/install.html).
1. Click **** → **Passwords and cards** or go to `browser://personal/contacts`.
1. Open **Personal data**.
1. Click **Add** and fill out the form.
1. To add other fields to the form, click **Add field**.
1. Click **Save**.
If forms on the site have **Passwords** and **Bank cards** fields, enter this data as well.
## Step 2. Check autofill in the form {#check}
Click all the fields of the form on your site and check whether the autofill hints are displayed correctly.
## Step 3. Make any necessary edits {#edits}
If there aren't any hints or the hints are displayed incorrectly, make sure the form markup follows the recommendations below.
## Markup recommendations {#recommend}
Make sure that:
- The form markup [meets HTML standards](https://html.spec.whatwg.org/).
- The input element has the `autocomplete` attribute with a valid value.
For example:
{% cut "Name input field " %}
```html
```
{% endcut %}
{% cut "Email input field" %}
```html
```
{% endcut %}
For details, see [HTML Living Standard](https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofilling-form-controls:-the-autocomplete-attribute) and [MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/autocomplete#values).
- Data input elements are child elements of the `form` tag. For details, see [Submitting forms](#submit).
- Data input elements have intuitive attributes, for example:
#|
||
**Attribute**
|
**Field type**
|
**Possible name options**
||
||
`id`
|
First name
|
`first_name`, `name_first`, `fname`, `firstname`, `given_name`, `givenname`
||
||
`name`
|
Phone number
|
`phone`, `phoneCity`, `telephone`, `tel`
||
||
`placeholder`
|
Organization
|
`org`, `organization`, `company`
||
|#
{% cut "Example of code that is understandable for autofill" %}
```html
```
{% endcut %}
{% cut "Example of incorrect code" %}
```html
```
{% endcut %}
- The value of the `for` attribute of the `label` tag unambiguously refers to the input element that it was intended for.
{% cut "Example of the label tag that is understandable for autofill" %}
```html
```
{% endcut %}
{% cut "Example of incorrect code" %}
```html
```
{% endcut %}
## Submitting forms {#submit}
The browser recognizes most of the data entered by the user during the form submission process. When the form doesn't have the `form` tag on the site and there is no explicit `submit` event to submit a form, the data stored in the browser and autofill may not work correctly.
Several mechanisms are used to recognize the submission. The simplest one is processing a `submit` JavaScript event. There are also heuristics that analyze the filling in of form fields, save the entered data, and respond to:
- Navigation on the site.
- AJAX requests.
- Deleting `iframe`s that a form was completed inside of.
- Deleting or hiding filled elements.
Heuristics sometimes cause a false trigger and may save incorrect data. The process becomes especially complicated if the `form` tag is missing. The browser is forced to find fields, consider them a single form, and analyze their completion.
In order for the browser to save the entered data so that the user can fill out the form with one click on the next visit to the site, it is important to prepare the submission form correctly: use the `form` tag and inside it define `input type="submit"`.
{% cut "Example of a simple and clear submission form" %}
```html
```
{% endcut %}
{% cut "Example of a complex but understandable submission form" %}
```html
```
{% endcut %}
{% cut "Example of a submission form that is not understandable to the browser" %}
```html
Button
```
{% endcut %}
## How to disable autofill on the site {#how-to-off}
If you only want to disable autofill because it doesn't work correctly, contact the Yandex Browser team at [browser-autofill@support.yandex.ru](mailto:browser-autofill@support.yandex.ru). Our experts will help you get autofill set up. If you have other reasons for disabling it, try the following non-standard solution:
{% cut "autocomplete="none" " %}
Any invalid value of the `autocomplete` attribute signals the browser to disable autofill. In addition to `none`, you can use the values `nope`, `all-off`, `smth`, or any other arbitrary set of letters.
{% endcut %}
The Yandex Browser team can't guarantee that this method will work in every environment. To see if you disabled autofill, click the form fields and make sure that there are no hints.
