The Moralis Auth API creates wallet-signing challenges, verifies signatures, and returns a profileId that your app can use to identify the authenticated user. It does not create your app's user database or manage your app's session for you.
Your application is responsible for storing any app-specific user profile, preferences, and session data it needs. The earlier statement that Moralis stores no user data was too broad. For information about data Moralis processes and retention, see the Moralis Privacy Policy.
