# Can I Use the Same API Key or Secret Token for Message Encryption?

No, the **API key** and the **secret token** for **[message encryption](https://www.smsgatewaycenter.com/developer-api/encrypt-sms-message/)** are distinct and must be used separately. **SMSGatewayCenter** provides a **unique secret token for API authentication** and another **separate secret token for message encryption**, each serving different purposes to ensure the security of your account and messages. The **API key is used to authenticate requests to our API endpoints**, while the **message encryption token is required to encrypt/decrypt message** data stored in our system or downloaded reports.

To protect your account and messages effectively, you must store both tokens securely (e.g., in a password manager, secure vault, or encrypted configuration file) and never share them publicly. Using separate tokens prevents a single point of failure and enhances security by limiting exposure if one token is compromised. For assistance on generating, managing, or securing these tokens, contact our support team at [contact@smsgatewaycenter.com](mailto:contact@smsgatewaycenter.com).
