mysql> GRANT ALL PRIVILEGES ON databasename.* TO "wordpressusername"@"hostname" IDENTIFIED BY "password";
Query OK, 0 rows affected (0.00 sec)
  
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

mysql> EXIT
Bye
$ 

With the latest version of mysql it looks like you need to first create the user and then do a "grant all".

i.e.:
create user "wordpressusername"@"hostname" identified by "password";
grant all privileges on databasename.* to "wordpressusername"@"hostname";

for some reason wordpress wouldn't connect to it.
This solved it though
ALTER USER 'username'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
