The api_behavior and signup_behavior parameters control how Auth0 handles users without passwords and password requirements on signup.

How do the API and signup behavior parameters function?

Configure the Passwordless Authentication on Database Connections feature, which is in Early Access (EA) as of August 2026, by setting the API and signup behavior parameters.

• The api_behavior parameter corresponds to the Support users without a password setting. Setting this value to required disables the Support users without a password feature.
• The signup_behavior parameter corresponds to the Password on signup setting.
