Change language on Single Sign On

How do I change the language on the single sign on login page?

I see that the Lock has a language option but I cannot use the Lock with SSO.

I found the answer myself. The SSO login page is just a Lock that is hosted on Auth0. So I need to enabled “Hosted pages” and configure the Lock there.

The hosted pages can be customized from: https://manage.auth0.com/#/login_page
