MySQL: Error 1045 – Access denied for user

In this article, we are going to create a new MySQL user and discuss all related aspects of it. And in the process, we will solve MySQL Error 1045 (Access denied for user).

Error Details

Error Number1045
MessageAccess denied for user ‘%s’@’%s’ (using password: %s)
Possible Reason1. Access/Permission not granted for the user.
2. Remote access to the server is not allowed for that user.
3. Remote access to the server is not allowed at all (No remote access allowed).
Error TypeServer-Side Error

Let’s see how can we address all these possible reasons and solve the issue.

Using all the following queries, we are creating a user named myuser and password will be test1234.

Login to MySQL and execute the following query.

Create user

Create a new user that can be accessed from localhost:

CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'test1234';

Grant permission

Give all permission to the user:

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'localhost';

To give the user permission to only one database (say, DB name is testdb) use the following command:

GRANT ALL PRIVILEGES ON tested.* TO 'myuser'@'localhost';

Then you need to flush/reload the privilege:


Allow Remote access

If you want to change the host and want it to be accessed from any computer:

UPDATE mysql.user SET Host=‘%’ WHERE Host='localhost' AND User='myuser';

Also, use the following command to reflect the permission changes immediately:


Additionally, if you want it to access the MySQL server from a remote computer, then in the MySQL configuration file, comment the following line (if it is not already commented)

# bind
