Keychain Not Saving Passwords on iPhone 18 Pro? How to Fix

It can be very frustrating when Keychain doesn’t fill your passwords like you expect. Most people have far too many passwords to remember and so rely on a password manager like iCloud Keychain. If your password doesn’t get stored in Keychain, you may have to reset your password, which is pretty inconvenient.

In this article, we will outline some troubleshooting steps to help you solve the issues with your iCloud Keychain when you have one of the following problems:

Keychain fills in the wrong password.
Mac or iPhone Keychain isn’t remembering your passwords.
iCloud Keychain isn’t filling in user names and passwords
Keychain isn’t syncing your passwords among your devices.

See if a password is saved (correctly) in Keychain

If a password is not filling in correctly, you can check if it is saved in Keychain. Sometimes, you may have an incorrect password saved in Keychain. Other times, websites may use more than one login page address, which can cause issues with Keychain.

See your Keychain passwords on iPhone 18 Pro

Go to the Passwords app on your iPhone and tap All. The passwords should unlock with Face ID.
You can find the website name by scrolling, tapping a letter on the right or using the search field at the top.
Tap on the website to view the password.

If you don’t see any passwords, check that you have Keychain turned on for your iPhone 18 Pro. Open Settings and tap on your Apple Account name at the top. Select iCloud. Tap See All (next to Saved to iCloud), then tap Passwords & Keychain. Turn on Sync this iPhone, then follow the onscreen instructions.
