This is identical to what PASSWORD('') in MySQL does:
5.6.22-debug-log> CREATE USER 'testpwd'@'localhost' IDENTIFIED BY 'foo';
Query OK, 0 rows affected (0.03 sec)
5.6.22-debug-log> SELECT User,Host,Password FROM mysql.user WHERE
User='testpwd';
+---------+-----------+-------------------------------------------+
| User | Host | Password |
+---------+-----------+-------------------------------------------+
| testpwd | localhost | *F3A2A51A9B0F2BE2468926B4132313728C250DBF |
+---------+-----------+-------------------------------------------+
1 row in set (0.01 sec)
5.6.22-debug-log> SET PASSWORD FOR 'testpwd'@'localhost' = PASSWORD('');
Query OK, 0 rows affected (0.00 sec)
5.6.22-debug-log> SELECT User,Host,Password FROM mysql.user WHERE
User='testpwd';
+---------+-----------+----------+
| User | Host | Password |
+---------+-----------+----------+
| testpwd | localhost | |
+---------+-----------+----------+
1 row in set (0.00 sec)
