❓ Frequently Asked Questions
What makes a strong, unique password?
A strong password is long (12+ characters), uses a mix of letters, numbers, and symbols, and is unique for each account. Avoid common words or personal details; consider using a password manager to generate and store them.
Why is keeping software up to date important for file security?
Updates fix security vulnerabilities and improve defenses. Using the latest versions reduces the risk of attackers exploiting flaws to access or alter your files; enable automatic updates when possible.
What is two-factor authentication and how does it protect files?
Two-factor authentication requires a second proof of identity (like a code from an app or hardware key) in addition to your password. Even if a password is stolen, the attacker would still need the second factor to access files.
How does encrypting sensitive files help?
Encryption makes data unreadable without the decryption key, protecting files at rest and in transit from unauthorized access. Keep keys secure and separate from the encrypted data.
Why are backups essential for digital file security, and how should you back up?
Backups protect against data loss from hardware failure, user error, or malware. Use regular, versioned backups stored securely (offline or reputable cloud), and periodically test restoration.
