What type of connection method allows access without a password for the account in the Vault?

The correct choice for a connection method that allows access without a password for the account in the Vault is Single Sign-On.

Single Sign-On (SSO) is a user authentication process that allows a user to access multiple applications or systems with one set of login credentials. In the context of CyberArk, SSO enables users to authenticate once and gain access to various services, reducing the need for multiple usernames and passwords. This capability is essential in environments where ease of access and user convenience are necessary, while still maintaining a secure access framework.

While Secure Connect, Direct Connect, and Credential Vault each serve distinct purposes within CyberArk's architecture, they do not specifically enable password-less access in the same streamlined manner as SSO. Secure Connect typically refers to the method of ensuring safe connections to managed systems. Direct Connect could refer to establishing direct, encrypted pipelines for communication, which still rely on some form of credential management. Credential Vault primarily serves as the secure storage for sensitive credentials rather than a method for enabling password-less connections.
