Pre-production identity

Set up your Meridian workspace

One verified identity can enter as an individual, submit an organization for sandbox review, and keep every decision attributable without storing a public email in governance records.

Setup required

Sign in before creating a profile

Use the public Sign in with ChatGPT flow. Registration, email verification, password recovery, and optional MFA are handled by the identity provider; Meridian never stores a password.
