Which UI do you use?

Custom UI

Pre built UI

Provide SMTP configuration

Using this method, you can:

• Send emails using your own domain
• Optionally customise the default email templates and subject.

NodeJS

Important

For other backend frameworks, you can follow our guide on how to spin up a separate server configured with the SuperTokens backend SDK to authenticate requests and issue session tokens.
