How to store my Apple ID on my iPad so that it shows up in passwords?

Hi princeofthePI,

Welcome to Apple Support Communities. We understand that you'd like to have your Apple ID stored in your iPad passwords so you can access it later. We'd like to help.

When entering your Apple ID in the past, have you been given the option to save the password? If not, let's have you try to enter your Apple ID in the Apple ID website to see if you're prompted to save that information.

If that doesn't auto save, you can check out these steps to work on troubleshooting that:

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.
