Final answer:
By default, user certificates allow for Client Authentication, securing email communication, use with the Encrypting File System for file protection, and Document Signing.
Step-by-step explanation:
The user certificate is a digital certificate used mainly for securing online transactions and communications. By default, user certificates are configured to allow certain activities to ensure a secure environment for these transactions. The usages allowed by default typically include:
- Client Authentication: This allows users to authenticate themselves to a service or application, ensuring secure access.
- Secure Email: User certificates can be used to sign and encrypt emails, ensuring they can be read only by the intended recipients.
- Encrypting File System (EFS): This enables users to encrypt files on a Windows-based system, protecting sensitive data.
- Document Signing: Certificates are used to verify the integrity and origin of documents.
