Hey!
We have released a new vanilla JS SDK: supertokens-web-js, which provides session management, and helper functions for all the login methods / recipes so that it's easier for you to build your custom UI.
We have also added new docs for Angular integration with our react SDK, so that you can use SuperTokens' UI in your angular app.
SuperTokens is an open source authentication solution offering features like: Different types of login: Email / password, Passwordless (OTP or Magic link based).
