+## Configuring localization for authentication endpoints
+
+WSO2 Identity Server provides internationalization support for its web applications (such as the authentication endpoint located in the `<IS_HOME>/repository/deployment/server/webapps/` directory). The following steps describe how you can configure this:
+
+1. Navigate to `<IS_HOME>/repository/deployment/server/webapps/authenticationendpoint/WEB-INF/classes/org/wso2/carbon/identity/application/authentication/endpoint/i18n/`
+
+2. Duplicate the `Resources.properties` file in the same location and rename it with the required locale suffix as follows:
+    - For British English: `Resources_en_GB.properties`
+    - For French (Standard): `Resources_fr.properties`
+
+   Refer to [Web browser language identification codes](https://www.localeplanet.com/icu/) for more information on locale suffixes.
+
+3. Update the values for each key as follows:
+   ```
+   login=<Value in the required locale>
+   ``` 
+
+4. Save the file.
+
+5. Navigate to `<IS_HOME>/repository/deployment/server/webapps/authenticationendpoint/WEB-INF/classes/` and open the `LanguageOptions.properties` file.
+
+6. Add information about the new language in the following format & save the file.
+   ```
+   <language switcher name>=<language code>,<language name>`
+   ```
+
+7. Go to the browser settings and add the language you configured above.
+
+8. Restart the server. To try out, do the following:
+    1. Open up a browser.
+    2. Type the My Account portal URL. (If you are running the server in your localhost, the URL is: [https://localhost:9443/myaccount/](https://localhost:9443/myaccount/)). You will see the login screen having the contents in the configured language.
+
+## Configuring localization for recovery endpoints
+
+You can enable localization for `accountrecoveryendpoint` by applying the same steps 1 through 8 in the previous section, for the following location:
+
+`<IS_HOME>/repository/deployment/server/webapps/accountrecoveryendpoint/WEB-INF/classes/org/wso2/carbon/identity/mgt/recovery/endpoint/i18n/`.
+
+Update the LanguageOptions.properties file located at: `<IS_HOME>/repository/deployment/server/webapps/authenticationendpoint/WEB-INF/classes/LanguageOptions.properties` to include the new language options.
