Additional Information

When deciding on a new passcode for your iPhone 15, it’s crucial to choose something non-obvious. Steer clear of easily guessable codes like “123456” or your birthdate. Instead, opt for a random combination that’s meaningful only to you. Think of it as coming up with a secret handshake that only you and your closest pals know. Additionally, enabling the “Erase Data” feature adds another layer of security, wiping your phone clean after ten incorrect passcode attempts.

It’s the digital equivalent of a self-destruct mechanism for safeguarding top-secret information. Lastly, always ensure your iPhone’s software is up to date, as this can also affect your phone’s security.
