Frequently Asked Questions
Q: Which is safer, Touch ID or Face ID?
A: Both have very high security levels, but Face ID uses more advanced technology and is considered harder to forge. However, considering mask-wearing convenience, Touch ID is also a valid choice.
Q: Is iCloud backup safe?
A: iCloud backups are encrypted and even Apple cannot view the contents. However, for higher security, we recommend enabling "Advanced Data Protection for iCloud."
Q: What if I forget my passcode?
A: If you forget your passcode, you need to restore iPhone using iTunes or Finder. However, this erases all data, making regular backups important.
Q: Is factory reset sufficient?
A: Factory reset is sufficient for general purposes, but for confidential information or corporate use, we recommend specialized data erasure tools. MASAMUNE Erasure enables secure erasure and certificate issuance.
