On PHP versions < 8.2, this change will have no effect.
On PHP versions >= 8.2, this change will slightly improve the security of the login process by identifying to PHP that the $pass parameter is "sensitive". When the content of a parameter would normally appear in error logs (e.g., when some kind of error occurs, PHP crashes, etc), or when it would normally be displayed via var_dump(); or similar, if the parameter has been marked as "sensitive", instead of the normal content, something like Object(SensitiveParameterValue) would be displayed, helping to reduce the risk of such sensitive content being leaked.
The sensitive parameter attribute isn't available for PHP versions < 8.2. However, for PHP versions < 8.2, when the content of a line in some PHP code begins with a hash (#), it is treated the same as a comment (e.g., // like this), so, as long as the sensitive parameter attribute is kept on its own line, backwards-compatibility problems should be avoidable (i.e., it won't cause errors, won't cause PHP to crash, etc).
