You can set the default authentication method displayed on the Self-Service Portal depending on your organization's and users' needs.
This setting is only accessible at the Global level for on-premises customers.
Configure this setting by navigating to Groups & Settings > All Settings > Installation > Advanced > Other and set the SSP Authentication Type to:
- Email – Prompts users for only their email address if you have set up auto discovery.
- Legacy – Prompts users for their Group ID and credentials (username/password).
- Dedicated – Prompts users for only their credentials (username/password). This option defaults a single Group ID for single-customer environments.
