Update iOS Device

You can update your iPhone, iPad, or iPod touch to the latest version of iOS or iPadOS wirelessly.* If you can't see the update on your device, you can update manually using your computer.

If a message says that an update is available, tap Install Now. You can also follow these steps: 

1. Plug your device into power and connect to the Internet with Wi-Fi.
2. Go to Settings > General, then tap Software Update.
3. Tap Download and Install. If a message asks to temporarily remove apps because the software needs more space for the update, tap Continue or Cancel. Later, iOS or iPadOS will reinstall apps that it removed.
4. To update now, tap Install. Or you can tap Later and choose Install Tonight or Remind Me Later. If you tap Install Tonight, just plug your device into power before you go to sleep. Your device will update automatically overnight.
5. If asked, enter your passcode.

Set a Passcode on iPhone

For better security, set a passcode that needs to be entered to unlock iPhone when you turn it on or wake it. Setting a passcode turns on data protection, which encrypts your iPhone data with 256-bit AES encryption. (Some apps may opt out of using data protection.)

Set or change the passcode

1. Go to Settings, then do one of the following:
   • iPhone X and later: Tap Face ID & Passcode.
2. Tap Turn Passcode On or Change Passcode.

To view options for creating a password, tap Passcode Options. The most secure options are Custom Alphanumeric Code and Custom Numeric Code.

After you set a passcode, you can use Face ID or Touch ID to unlock iPhone (depending on your model). For additional security, however, you must always enter your passcode to unlock your iPhone under the following conditions:

• You turn on or restart your iPhone.
• You haven’t unlocked your iPhone for more than 48 hours.
• You haven’t unlocked your iPhone with the passcode in the last 6.5 days, and you haven’t unlocked it with Face ID or Touch ID in the last 4 hours.
• Your iPhone receives a remote lock command.
• There are five unsuccessful attempts to unlock your iPhone with Face ID or Touch ID.
• An attempt to use Emergency SOS is initiated (see Make emergency calls on iPhone).
• An attempt to view your Medical ID is initiated (see Create a Medical ID in Health on iPhone).

Set up Face ID on iPhone

Use Face ID (iPhone X and later) to unlock iPhone, authorize purchases and payments, and sign in to many third-party apps by simply glancing at your iPhone.

To use Face ID, you must also set up a passcode on your iPhone.

Set up Face ID or add an alternate appearance

• If you didn’t set up Face ID when you first set up your iPhone, go to Settings  > Face ID & Passcode > Set up Face ID, then follow the onscreen instructions.
• To set up an additional appearance for Face ID to recognize, go to Settings > Face ID & Passcode > Set Up an Alternate Appearance, then follow the onscreen instructions.

Set up Touch ID on iPhone

Use Touch ID (supported models) to unlock iPhone, authorize purchases and payments, and sign in to many third-party apps by pressing the Home button with your finger or thumb.

To use Touch ID, you must also set up a passcode on your iPhone.

Turn on fingerprint recognition

1. If you didn’t turn on fingerprint recognition when you first set up your iPhone, go to Settings  > Touch ID & Passcode.
2. Turn on any of the options, then follow the onscreen instructions.

Add a fingerprint

You can add multiple fingerprints (both of your thumbs and forefingers, for example).

1. Go to Settings  > Touch ID & Passcode.
2. Tap Add a Fingerprint.
3. Follow the onscreen instructions.
