MySQL Error #1045: The Solution

In this mysql tutorial we'll explain the mysql error 1045. The MySQL Error 1405 looks like this:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

In this sql tutorial we'll explain how to overcome this sql error. Here's what could have gone wrong:
1) Host: You may be connecting to the wrong mysql server host. If the mysql server host is not specified, the MySQL Server will try to connect to localhost, so keep that in mind.

2) User: If the host you're connecting to is correct, the MySQL server user may not exist. Double check if it exists, and if not, create a new user by running a sql query like so:
CREATE USER 'demo_user'@'localhost' IDENTIFIED BY 'strongpassword';

3) Permissions: If your MySQL server user exists, double check if he has the permissions to connect.

[mysqld]
user=username
password=password

mysql -u [user] --ssl-mode=REQUIRED
