Support Multi-Language Embedded Logins with the Locale Parameter

Add dynamic language support for Embedded Login simply by setting the locale-code parameter in your Embedded Login script. Localize your login page for every language that your website supports.
Available in: Professional, Enterprise, Performance, Unlimited, and Developer Editions

Embedded Login takes advantage of the multi-language support that browsers provide. Set the locale-code parameter dynamically in the Embedded Login script tag <script> of your webpage. This example displays the embedded login page in Japanese.

<script src="https://embeddedlogin-developer-edition.na99.force.com/demo/servlet/
servlet.loginwidgetcontroller?type=javascipt_widget&locale=jp" async defer></script>
