The new line is: ALTER USER 'mythtv'@'localhost' IDENTIFIED WITH mysql_native_password;
(assuming mythtv is the user being created if it doesn't exist and then altered.)

Please mention your SQL version.

If you try the above ALTER... does it remove your password. It didn't in my tests
and per the help pages (at least my reading of them.) There is a RETAIN CURRENT PASSWORD
option, but I'm not certain that it works for all versions of MariaDB and MySQL. There's
also mentioned of it applying to a secondary password.
