What is the role of Master Key in CyberArk?

The Master Key in CyberArk serves as a critical component in the recovery operations for the vault that contains sensitive information, such as credentials and secrets. It is utilized to encrypt and decrypt the keys used to secure the stored data. In scenarios where disaster recovery is necessary, the Master Key allows administrators to regain access to the vault, ensuring that the data remains secure while also being recoverable in case of issues such as corruption or loss of access.

In the context of other roles mentioned in the choices, the Master Key does not facilitate user logins directly, nor does it manage access controls or secure audit logs. Its primary function is centered around enabling reliable recovery solutions, thereby emphasizing its importance in maintaining the integrity and accessibility of sensitive data within CyberArk's architecture.
