In the current mandate, we are using Auth0 Lock UI v9.2.2.
There happen to be a bug with the widget where the following text is hardcoded.
Single Sign-on Enabled
To fix this issue in our AngularJS Single Page Application, we had to introduce this in the
<style ng-if="myLanguage == '<LANG HERE>'">
This piece of code fixes the issue when a specific language is specified.
ng-if will completely remove the tag when the language won’t match and monkey patch the text.
If you have more than 2 languages, it would pay to consider injecting the text directly within the style tag. Since Angular doesn’t allow you to parse it, somebody else already documented how to do it.
