how do i turn off the app specific password

App specific passwords are single use and do not need to be remembered.

Two factor authentication cannot be turned off, it is an Apple policy requirement.

All your other passwords are in Settings, Passwords and can also be copied into a password protected document in iCloud if you want additional copies.

Question no answered. How is App Specific Passwords turned off? Two factor OK but not App Specific Passwords.

If an app requires a passcode to get into it, there is no way to turn that off.
