Out of the box, Authgear provides multiple languages that your application can display. If a language you wish to use is not in the list of built-in languages, you can still add your own translation.json to add support for the language.

Authgear will display text in a language based on your user's locale. In case the user's locale does not match any of the available languages for your project, the primary language will be used.

In this guide, you'll learn how to enable a supported language, set the primary language for your project, and add more languages using custom translation.

To access the Language settings for your project, navigate to the Languages section in the Authgear Portal.

1. Enable a Supported Language

You must enable a language before you can set it as a primary language or customize it. To enable a language, go to the Languages section in the portal, scroll to the language (built-in or custom translation), and check the box next to it. Finally, click on the Save button on the top left corner of the screen to keep your changes.
