Add the Save in 1Password button to your website

Learn how to add the Save in 1Password button to your website, so customers can save an item to 1Password with a click.

When you add the Save in 1Password button to your website, visitors can easily save their sign-in details, credit cards, or addresses to their 1Password account with a click. If you set up an integration with 1Pasword, the button can also be used to save API keys.

The Save in 1Password button on your site communicates directly with 1Password in the browser, so no unencrypted information leaves the customer’s browser.

Step 1: Add the button to your site

To add the button to your site, you’ll need to install the Save in 1Password button, build a save request, and import the button into your file with the required attributes and values. The button is disabled by default. When the page loads, 1Password will check for the button and make it available to the user. Item URLs, if applicable, are determined by 1Password, so a login item can only be filled for the domain on which it was saved.

The button element specifies the type of item to create and the information it’ll contain. The information is a Base64-encoded save request in JSON format.

1.1 Install the button

To get started, install the Save in 1Password button using your preferred package manager:

npm

npm install @1password/save-button --save-dev

Yarn

yarn add @1password/save-button -D

Then import the package into your HTML file. For example:

<script type="module">
    import "@1password/save-button/index.js";
</script>

1.2 Build a save request

The save request needs these values:

Field Type Description
title string The suggested title for the item to be saved.
fields array Each object in the array has these properties:
  • autocomplete (string): The type of field to fill.
  • value (string): The value to be filled in the field.

Use the autocomplete field name and values defined in the "Autofill" section of the HTML Living Standard.

notes

(optional)

string Notes to save with the item. These can be formatted with Markdown.

For example:

{
  "title": "ACME Credit Card",
  "fields": [
    {
      "autocomplete": "cc-name",
      "value": "Wendy J. Appleseed"
    },
    {
      "autocomplete": "cc-number",
      "value": "4111111111111111"
    },
    {
      "autocomplete": "cc-exp",
      "value": "202512"
    },
    {
      "autocomplete": "cc-csc",
      "value": "123"
    },
    {
      "autocomplete": "cc-type",
      "value": "visa"
    },
    {
      "autocomplete": "street-address",
      "value": "512 Main Street"
    },
    {
      "autocomplete": "address-level2",
      "value": "Cambridge"
    },
    {
      "autocomplete": "address-level1",
      "value": "MA"
    },
    {
      "autocomplete": "postal-code",
      "value": "12345"
    },
    {
      "autocomplete": "country",
      "value": "US"
    }
  ],
  "notes": "Plain text. You can use [Markdown](https://support.1password.com/markdown/) too."
}

1.3 Add the button to your page

Add the Save in 1Password button to your page with the two required attributes: data-onepassword-type and value. You can also add an optional lang attribute if you want to localize the button language.

Attribute Value
data-onepassword-type The type of item the button will create:
credit-card, identity, or login
value The Base64-encoded save request.
lang

(optional)

The language code for one of the supported languages.

If no language attribute is provided, the package will determine the browser language using the NavigatorLanguage Web API. If the browser language isn’t supported, the package will default to English.

For example:

<onepassword-save-button
       data-onepassword-type="credit-card"
       value="ewoJInRpdGxlIjogIkFDTUUgQ3JlZGl0IE...=="
       lang="en">
</onepassword-save-button>

If you’re building a single-page app, dispatch a CustomEvent on the page with type OPButtonAdded to tell 1Password to enable the Save in 1Password button.

Step 2: Request to be added to the list of allowed sites

The Save in 1Password button only works on sites approved by 1Password. To request that your site be added to the list or for more information about the Save in 1Password button, contact the 1Password Partnerships team.
