TypoScript

Templating

Backend Login

You have also the option to use your own template files for the backend login. Just adapt the following TypoScript constants:

module.tx_auth0 {
    view {
        layoutPath = EXT:your_key/Resources/Private/Layouts/
        templatePath = EXT:your_key/Resources/Private/Templates/
    }

    settings.stylesheet = EXT:your_key/Resources/Public/Styles/Backend.css
}

Please make also sure that you configure the admin-typoscript-rolemapping from Auth0 roles to TYPO3 user groups. Maybe you also want to set the admin flag for backend users, depending on an Auth0 admin-typoscript-propertymapping.
