Your Organization Admin can enable SAML-based Single Sign-On (including Just-In-Time (JIT) provisioning with SAML) for your Persona Dashboard. Then users can log in with their email or with their organization slug.
First-Time User Login
First-time users must log in with their organization slug. This completes the provisioning of their account. It is also an added security measure.
Subsequent Login
After the first login, users can log in to the Persona Dashboard with their organization slug or with their email.
