If you don't see your iCloud Keychain items 

There are several possible reasons for why you can't find your iCloud Keychain information.

Did you restore from an iCloud backup and then notice missing iCloud Keychain items?

iCloud Keychain items aren't part of iCloud backup because they already live in the cloud. To see if iCloud Keychain is turned on, in iOS 10.3 or later, tap Settings > [your name] > iCloud > Keychain. For iOS 10.2 or earlier, tap Settings > iCloud > Keychain.

Did you turn off iCloud Keychain on all your devices? 

If so, your iCloud Keychain is removed from the cloud. If you chose to delete the keychain items from your devices when you turned off iCloud Keychain, your iCloud Keychain is also removed from those devices. You need to set up iCloud Keychain and add items again.

If you turn off iCloud Keychain on all your devices, and choose to delete your iCloud Keychain locally on all your devices, this also deletes your Keychain data from iCloud servers.

On your Mac, did you use Keychain Access to reset your iCloud Keychain? 

If so, macOS deleted your iCloud Keychain items. Try to set up iCloud Keychain again. If you need to reset your Mac Keychain again, temporarily disable iCloud Keychain in iCloud Preferences before you reset your macOS Keychain.

If iCloud Keychain is on, but Safari won't save or AutoFill account or credit card information

If Safari doesn't autofill your account names, passwords, or credit cards, or doesn't ask to save them, make sure you have the latest version of iOS and macOS on your devices. If the issue remains, follow these steps to check the AutoFill and Private Browsing settings on your device.

On your iPhone, iPad, or iPod touch with iOS 10 or later

1. For account names and passwords:

• iOS 14 or later: Go to Settings > Passwords > AutoFill Passwords. Check that AutoFill Passwords is turned on. 
• iOS 12 or 13: Go to Settings > Passwords & Accounts > Website & App Passwords. Check that AutoFill Passwords is turned on.
• iOS 10 or 11: Go to Settings > Safari > AutoFill. Check that AutoFill Passwords is turned on.

2. For credit card information, go to Settings > Safari > Autofill. Check that Credit Cards is turned on.

3. Open Safari. If the navigation bar in Safari is black or dark instead of white or light gray, turn off Private Browsing. Safari doesn't save account names and passwords when Private Browsing is on. 

Still need help to autofill credit card information? In Safari, tap the credit card field, then tap AutoFill Credit Card above the keyboard.

On your Mac with OS X Mavericks or later

1. Choose Safari > Preferences, then click AutoFill.
2. Make sure User names and passwords is selected. For credit card information,* make sure Credit cards is selected.
3. See if you turned on Private Browsing. Safari doesn't save account names and passwords when Private Browsing is on.

Still need help to autofill credit card information? In Safari, click a credit card field to see the message that asks you to choose which credit card to use from your iCloud Keychain.

* Always enter your card's security code manually. iCloud Keychain doesn't store credit card security codes.

If Safari won't save the password for one of the websites that you're using

Some websites request that passwords not be saved. Safari won't save or autofill account names and passwords on those sites.

If you didn't receive the verification code through SMS

If you use two-factor authentication, the steps below don't apply because you won't have a separate SMS verification number for iCloud Keychain. Check if you use two-factor authentication, then check that the phone number associated with your account is correct.

Check if you use two-factor authentication

• On your iPhone, iPad, or iPod touch: tap Settings > [your name], then tap Password & Security.
• In macOS Catalina or later: choose Apple menu  > System Preferences > Apple ID, then click Password & Security.
• In macOS Mojave or earlier: choose Apple menu  > System Preferences > Apple ID, then click iCloud. Then click Account Details.

Check or update your phone number

If two-factor authentication is off, use these steps to check that your phone number is correct or update your phone number.

1. Make sure that you have a strong cellular network connection on your phone.
2. Make sure that your phone number can get SMS messages. To check, ask someone to send you a text message.
3. Make sure the correct phone number is associated with your account. Here's how:

• On your iPhone, iPad, or iPod touch, tap Settings > [your name] > iCloud > Keychain > Advanced.
• On your Mac, choose Apple menu  > System Preferences, then click Apple ID. Click iCloud in the sidebar, then select Keychain. If you're using macOS Mojave or earlier, click iCloud, then click Options next to Keychain. 

1. Make sure that the phone number under Verification number is correct.

If you can't change the SMS verification phone number for iCloud Keychain

1. If you have a device with iCloud Keychain already turned on, try these steps first to change your iCloud Security Code:

• On your iPhone, iPad, or iPod touch, tap Settings > [your name] > iCloud > Keychain > Advanced and tap Change Security Code.
• On your Mac, choose Apple menu  > System Preferences, click Apple ID, then click iCloud in the sidebar. Select Keychain. If you're using macOS Mojave or earlier, click iCloud, then click Options next to Keychain. Choose "Change Security Code..."

1. After you change the iCloud Security Code, try to change the SMS verification number again.
2. If you still can't change the SMS verification number, or if you can't access a device that has iCloud Keychain enabled, contact Apple Support and verify your identity to get help setting up iCloud Keychain."

We hope this helps.

Cheers!
