Use phone password instead of face ID for saved passwords

Apple also keeps using face ID on me whenever I log into my Apple ID, which I never opted into. I cannot find a setting to turn this off.

Logging into an Apple ID never requires Face ID.

Apple only asks for Face ID when you’re performing a local device action — like viewing saved passwords, auto-filling your Apple ID in a form, or approving a change in Settings. In those cases, Face ID is simply confirming it’s you using the device, not authenticating the Apple ID itself.

While iCloud Keychain doesn't directly store passwords for individual apps, it can store login credentials for websites associated with those apps. 

Here's how it breaks down:

• App-Specific Logins: When you log in to an app that doesn't have a web interface (think mobile games or music players), iCloud Keychain won't store those specific app passwords.
• Website Logins for Apps: If the app you're using has a corresponding website (like a social media app or online banking), iCloud Keychain can store the password you use for the website login. This is because the website login often uses the same credentials as the app itself.
• Autofill Convenience: When you revisit the website on Safari or another compatible browser, iCloud Keychain can then automatically fill in your login information based on the stored website credentials. In many cases, this same login information will also work for the app itself.

Here's an example:

• Imagine you use a social media app called "Chatter." "Chatter" doesn't have a website, so iCloud Keychain won't store a password specifically for "Chatter."
• However, "Chatter" might have a website at "chatther.com" where you can manage your account settings.
• If you log in to "chatther.com" on Safari and save your password with iCloud Keychain, it will remember those credentials.
• The next time you open the "Chatter" app, there's a good chance it will recognize the login information stored for "chatther.com" and allow you to log in to the app without needing to re-enter your password.

In short, iCloud Keychain focuses on storing website logins, but these website credentials can often be used for the corresponding apps as well.

iCloud Keychain (Apple’s built‑in manager):

• Go to Settings > Face ID & Passcode > Other Apps.
• Toggle off Face ID for apps where you don’t want it used.
• Then, in Settings > Passwords, look for Require Face ID. If enabled, it means once you unlock with Face ID, autofill happens without further checks. Unfortunately, Apple doesn’t allow per‑app verification prompts — it’s either Face ID or device passcode at unlock.

You may check this.

Did you not get a prompt as shown in the pic below when you logged into the App?

See the pic below here where you can find out which apps have access to Face ID. If you do see this on your iPhone then you will have to go into the settings of the App (Not iPhone Settings). You may also delete the app and re-install it.
