Yea. So you can use supertokens-website repo for sessions (works with plain JS). The docs are here: https://supertokens.io/docs/website/installation Then on the backend, you can use our supertokens-node SDK. Follow the backend quick setup: https://supertokens.io/docs/emailpassword/quick-setup/backend. This would expose APIs for sign up / sign in / reset password etc etc using which you can build your frontend UI. The list of APIs are here: https://supertokens.io/docs/nodejs/emailpassword/default-apis And finally you would have to run the supertokens core which you can run yourself (see this page: https://supertokens.io/use-oss) or let us run for you (need to sign up for this).
