I loaded the password validation plugin in MySQL 5.7 on Ubuntu Server 16.04 to leave the system with more protection, but it seems that this plugin forces all passwords to comply with certain rules and ends up that none is correct giving this error: / p>
error 1819 (hy000) your password does not satisfy the current policy requirements
Solution:
Type in the Linux terminal (Ubuntu), then enter the root password (admin) of linux:
sudo mysql -h localhost -u root -p
It will go into Mysql, see:
Now, inside mysql type:
uninstall plugin validate_password;
You will return the following message: Query OK, 0 rows affected (0.00 sec)
Ready!
Plugin disabled.
