TYPO3 Core

With User TSConfig it is possible to remove the password field from the backend user settings:

setup.fields {
    password.disabled = 1
}

This setting makes sense e.g. if you use alternative login providers like LDAP or oauth where the password field is not necessary.

When the password field is removed, it's not possible to save changed backend user settings:

PHP Warning: Undefined array key "password" in vendor/typo3/cms-setup/Classes/Controller/SetupModuleController.php line 238
