This wikiHow teaches you how to enable or change the password for your Keychain service, which stores passwords for all devices logged into your iCloud account.

Method 1

Method 1 of 2:

Changing an Existing Security Code

1
Open your iPhone's Settings. Do so by tapping the grey gear icon on one of your Home screens or in the "Utilities" folder.
2
Scroll to the fourth group of options and select iCloud. You may be prompted to enter your Apple ID password in order to continue.

3
Scroll to the bottom of the menu and select Keychain.
4
Tap Advanced. If you don't see this option, you'll need to sign out of your iCloud account and then sign back in. You can do this from the bottom of the iCloud menu.
- Make sure you choose Keep on my iPhone when asked where you want to store your iCloud data (e.g., contacts).
5
Tap Change Security Code.
6
Type in a security code. You can also tap Advanced Options to change the properties of your security code to one of the following options:
- Use Complex Security Code - Create your own alphanumeric (numbers, letters, and symbols included) code.
- Get a Random Security Code - This option generates a long string of numbers and letters to serve as your security code.
- Make sure you write this code down somewhere--otherwise, you may not be able to access your Keychain data.
7
Type in your security code again. This will confirm your choice.
8
Enter your Apple ID password.
9
Tap OK.
10
Tap Don't Change Passcode. This will leave your iPhone's passcode distinct from your Keychain passcode. Your iCloud Keychain security code should now be updated.

Activating the iCloud Keychain Security Code

1
Open your iPhone's Settings. The "Settings" app is the grey gear icon that lives on one of your Home screens. It may be inside of a folder named "Utilities."
2
Scroll to the fourth group of options and select iCloud. If you're enabling Keychain for the first time, you'll be prompted to create a passcode.
- You may be prompted to enter your Apple ID password in order to continue.
3
Scroll to the bottom of the menu and select Keychain.
4
Slide the Keychain button right to the "On" position. If doing this doesn't prompt you to create a passcode, you'll need to sign out of your iCloud account on your iPhone and then re-sign in. This solves a small glitch with the Keychain app.
- You can sign out of iCloud from the bottom of the iCloud menu. When doing so, be sure to select Keep on iPhone when asked where you want to store your iCloud data.
5
Select passcode option. You can do one of two things here:
- Tap Use Passcode to apply your phone's lock screen passcode to Keychain. If you don't have a passcode, you won't have this option.
- Tap Create Different Code to enter a Keychain-specific code.
6
Type in your Keychain passcode.
7
Enter your phone number.
8
Tap Next. After your phone number and passcode are verified, you'll be taken back to the Keychain menu. Your passcode should now be active.

Warnings

If you forget your password for your Keychain service, you may not be able to retrieve the Keychain information.
