Auth0 Login or Sign Up Page Fails to Show Translations for Unsupported Dialects
Last Updated:
Overview
The Auth0 User Interface (UI) locales feature renders the login page in supported languages and uses this variable in email templates. When the ui_locales parameter contains an unsupported dialect, such as fr-CH, Auth0 defaults the login page to English. Passing an extended string containing multiple locales resolves this issue by allowing the login page to display in a supported language while generating emails in an unsupported dialect.
Applies To
- Email Templates
- Universal Login
- Auth0
Cause
Auth0 does not support certain dialects, such as fr-CH. If the ui_locales parameter contains this dialect, Auth0 defaults the login page to English.
Solution
How is the translation issue resolved for unsupported dialects?
The User Interface (UI) locales parameter accepts an extended string that contains multiple locales. Configure the ui_locales parameter to pass a combined string value that includes both the supported language and the unsupported dialect.
