How to change your Apple ID and device passwords on an iPhone, and better protect your device
Your iPhone identity can be protected with two important passwords: one for your Apple ID account, and another password or passcode to unlock your phone.
You can change both passwords from the Settings app on your iPhone.
You can balance convenience against security by using a short passcode or a longer, more complex password to unlock your phone.

Despite the popularity of biometric security like Face ID and Touch ID, the reality is that passwords and passcodes aren’t going anywhere anytime soon — we’ll still be unlocking apps, services, and devices with secret codes for the foreseeable future.
Your iPhone probably has at least two passwords (or passcodes) that you regularly use: your Apple ID, which gives you access to services like iCloud, Find My iPhone, and the iTunes store; and the optional password or passcode which keeps your device locked when you’re not using it. Most people use a 4- or 6-digit numeric passcode to lock their phone for convenience, but you can optionally enter a longer numeric passcode or a full alphanumeric password if you prefer.
You can change both the Apple ID password and the iPhone’s passcode at any time from your iPhone.
