To defend against attacks where the user is physically coerced, Casa App features an Emergency Lockdown Button. Once activated on the mobile app, all functions that depend on Casa App or Casa API will no longer function. This prevents the app from making new transactions or from using the Casa signing portal to add a signature to an existing transaction. The lockdown can only be removed by a customer service representative after the customer requests a removal of the lockdown and the representative verifies the customer’s identity.
