# Communication Security

The Salesforce mobile app always uses highest level of secure communications and encryption to safeguard your data.

The Salesforce mobile app uses SSL/TLS v1.2 for Over-The-Air (OTA) communication encryption. All Salesforce OAuth authorization endpoints are HTTPS only.

Salesforce servers deny communication requests below TLS v1.2.
