Since introduced in iOS 7, iCloud Keychain enables iPhone and iPad users to save the newest Safari website usernames and passwords, credit card information, and Wi-Fi network information on all your approved Apple devices (iOS 7.0.3 or later, OS X Mavericks 10.9 or later). It would be a little too easy to forget these passwords, especially those not used so often.
To find and view saved Safari password, credit card information and Wi-Fi password on Apple devices using iCloud Keychain (mainly). Followed, I’ll explain detailed steps to find Safari password, credit card info and Wi-Fi password respectively.
To see saved credit card numbers on your iPhone or iPad, follow steps below:
Go to Settings à Safari à AutoFill
Type in your passcode or use Touch ID to access your credit card numbers
Tap on Saved Credit Cards option
Choose the credit card number whose information you want to view
Find and See Stored Wi-Fi Password on iPhone (both Jailbroken and Non-jailbroken)
Unlike the former, saved Wi-Fi passwords are not allowed to be accessed from any settings on your iPhone and iPad, unless you have been jailbroken. You could find plenty apps (such as WiFi Password) on Cydia store to help you find Wi-Fi password. However, if your iPhone is non-jailbroken, still, there are a couple workarounds you can try.
Tick 1: Use Keychain and iCloud Sync
Go to application folder àutilities folder to find Keychain. If your Mac is using the same Wi-Fi network, you can find and view Wi-Fi password from Keychain app window.
Sync Keychain with your iCloud account and also sync Keychain with your iPhone.
Save all the passwords that you've been used and copy them to Notes or Remainder, so that they can always be at your fingertips.
Tick 2: Log into Router with Default User
Head to Settings -->Wi-Fi.
Find the Wi-Fi network whose password you want to view. Tap on the "i" to view more information.
The Router IP address will be displayed. Type the Router IP address in Safari and click on Enter. You will be guided to the Router log-in panel page.
When you see the router model, you can attempt to login with default user/password. Or you can Google the exact default user/password for yourrouter model.
iCloud Keychain works with third-party apps, it’s highly suggested that you use some password management apps (like 1password) together with iCloud Keychain to better manage your passwords.
