# Security Credentials

In the Security Credentials section, you can access and manage the token used for authentication in the CRM open integration interface. The token serves as a means of verifying and securing the integration process.

Here are the key features and actions related to security credentials:

1. View Token: You can view the current token that is being used for authentication.
2. Refresh Token: If needed, you can refresh the token to generate a new one. This action is useful for security purposes or when a token has expired or needs to be updated.
3. Token Refresh Timestamp: The security credentials page also displays the timestamp of when the token was last refreshed. This information helps you track the token's usage and monitor its validity.
