The solution to the problem of MySQL login Access denied for user'root'@'localhost' (using password: YES) under windows is to reset the password.

If so, solve it by resetting the password.

1. Open cmd as an administrator and switch to the bin directory of MySQL

cd /d E:\mysql-5.6.37-winx64\bin

2. Close the MySQL service:

net stop mysql;

3. Input

mysqld --skip-grant-tables 

Enter. (–skip-grant-tables can skip permission table authentication when starting the MySQL service.)

4. Keep this DOS window open, open another DOS window, and enter mysql and press Enter, the MySQL prompt > will appear.

5. Connect to the permission database:

use mysql; 

4. Modify the password:

update user set password=password(“root”) where user=“root”;

(Don't forget to add a semicolon at the end).

5. Refresh permissions:

flush privileges;　

6. Quit quit;

7. Close another running command line window;

8. Log in with the username root and the new password root you just set

That's it.
