Is iPhone Passwords App Safe?
Yes, the Passwords app is very secure, as narrated above.
The iCloud Keychain will protect your data because it’s equipped with AES-256 encryption. This means that even Apple cannot access your passwords because they are encrypted and decrypted on your device.
In addition, all passwords saved in the app are protected by Face ID or Touch ID. It is more difficult for unauthorized users to access them.
More importantly, Apple enhanced its security feature with password monitoring. This feature compares your saved passwords with a list of known data breaches and immediately alerts you if any of your credentials are found to have been compromised.
For more security, you can consider using LightningX VPN. The same as Apple, LightningX VPN also provides advanced encryption algorithms AES-256-GCM and ChaCha20-Poly1305. These can ensure your password data will not be intercepted or deciphered during transmission.
Download LightningX VPN to add an extra layer for your password management.
