Oauth2 Single Sign On SSO Page Language

[aario.shahbany]

Hi,
How can I change login page language in OAuth2 Single Sign On?
Currently I have a URL like below:
https://domain.eu.auth0.com/u/login?&state=abcd1234
Is this a URL param? Is this a configuration option I have to send when receiving the token? Is this a settings anywhere in Auth0 configuration? I could not find any information about this on web.

Here is the solution:
Go to Auth0 Management Console
On left sidebar select Universal Login
Go to Login tab
Click on Customize Login Page
In HTML tab find the line:

language: language

Change it to your language code. For a list of language codes see [Lock Internationalization](http://Lock Internationalization)
You can also get the language from the callback url provided by your application. In our case it was:

language: config.callbackURL.split('/')[3]
      	.replace('at','de')
      	.replace('cz','cs')
      	.replace('dk','da')
      	.replace('ch-fr','fr')
      	.replace('ch-de','de')
      	.replace('ch-it','it')
      	.replace('uk','en'),
