## Payload Encryption Overview {#payload-encryption-overview}

User Account Management uses JWE to encrypt request and response payloads that carry sensitive data, such as personally identifiable information (PII).
You can manage your encryption keys from your [Developer Dashboard](https://developer.mastercard.com/dashboard).
