While changing the password, I got the error: ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

mysql> SHOW VARIABLES LIKE 'validate_password%';

The default level is MEDIUM, we can change it to LOW by using the below query. The LOW level required only password’s length to min 8 characters.

mysql> SET GLOBAL validate_password_policy=LOW;

Query OK, 0 rows affected (0.02 sec)

To make this setting permanent edit MySQL configuration (my.cnf) file and add below settings.

[mysqld]
validate_password_policy=LOW
