The correct answer to the question "Which of the following is used to secure data and passwords?" is Encryption.

Explanation:

1. Encryption: This is the process of encoding data or information in such a way that only authorized parties can access it. It ensures that sensitive data, including passwords, remains confidential and protected from unauthorized access.

2. Authorization: This refers to the process of granting or denying access to resources based on the permissions assigned to users. While it plays a role in security, it does not directly secure data or passwords.

3. Accountability: This involves tracking user actions and ensuring that individuals are held responsible for their actions within a system. It is important for security management but does not directly secure data.

4. Authentication: This process verifies the identity of a user or device. While it is essential for ensuring that the right individuals have access, it does not secure data by itself.

In summary, while all these concepts are crucial components of data security, encryption specifically refers to the protection of the data itself.
