Redeem it after sign-in. An invalid invite will not prevent signup.

No password is used. The email link is single-use and expires after 15 minutes. While you keep using Decision Models, your session stays signed in for up to 90 days at a time.

Verification comes first: confirm the email link (or sign in with Google), then accept the Terms and the Data Processing Agreement in the dashboard before your first API key is created. This page does not collect your credentials.
