How do I get my facebook password off of an old iCloud account

Hi there Maryalymc,

If you're using an iPhone, you would need to be signed in with that Apple ID in Settings with iCloud Keychain turned on, then follow these steps to view your saved passwords:

View saved passwords and passkeys in Settings

1. Tap Settings, then select Passwords. In iOS 13 or earlier, select Passwords & Accounts, then tap Website & App Passwords.

2. Use Face ID or Touch ID when prompted, or enter your passcode.

3. To see a password or passkey, select a website or app. 

- To delete a saved password or passkey, tap Delete Password or Delete Passkey.

- To update a password or passkey, tap Edit.

Take care.
