Localization and language customization
You can use the localization and language customization features to select which languages your user flow is available in to suit your applications and customers' needs. Microsoft provides 36 languages in Azure AD B2C, and if your required language isn't available, you can also provide your own translations for any language.
Once you have selected the languages that you want to make available to the user flow, you can provide a ui_locales
query string parameter from your application. When you make a request to Azure AD B2C that includes this query string parameter, your page will be translated to the locale you have provided in the query string.
