New Universal Login vs. Classic Universal Login
If you decide to authenticate users with Auth0's Universal Login, you have a choice of two implementations:
New Universal Login offers a simpler and faster experience for end-users. All current and future Universal Login development work goes into the New Universal Login only. However, some Classic Universal Login features are not yet available in New Universal Login.
Classic Universal Login uses JavaScript controls for each page. Auth0 no longer adds new features to the Classic Universal Login.
