MLS Plugin Slot — Account / Auth
If the chosen MLS provider offers user accounts (most do: IDX Broker, iHomeFinder, Showcase IDX), their login/registration/dashboard UI plugs in here.
Saved searches, favorite listings, new-listing alerts, and account settings are typically handled by the plugin.
Custom auth via AWS Cognito + DynamoDB is an option if needed, but keeps scope smaller to use the plugin's built-in account system.
