When your Organization Admin enables SAML-based Single Sign-On (including Just-In-Time (JIT) provisioning with SAML) for your Persona Dashboard, users can log in with either their email or their organization slug.

## First-Time User Login

First-time users are required to log in with their organization slug to complete the provisioning of their account and as an added security measure.

## Subsequent Login

After the initial login, users can choose to continue using either their organization slug or their email to log in to the Persona Dashboard.
