Hi, I'm trying to close signups to a service that uses Supertokens. Is there a single setting I can change in supertokens core that will prevent it from creating new users and issuing them auth tokens?

there is no way to switch off sign up from the core. you will have to do that via backend SDK customisations

ok thanks. I'm using the emailpassword and third-party one. I found this article and I'm trying it out in staging: https://supertokens.com/docs/thirdpartyemailpassword/common-customizations/disable-sign-up/thirdparty-changes

right yea. Thats the correct thing to follow 🙂
