Access denied for user ‘[email protected]’ (using password:NO)

I’m new to MySQL, I’m trying to run WordPress in my Windows desktop and it needs MySQL.

I install everything with Web Platform Installer which is provided by Microsoft. I never set a root password for MySQL and in the final step of installing WordPress, it asks for a MySQL server password.

What is the default password for root (if there is one) and how to change it?

I tried:

mysql -u root password '123'

But it shows me:

Access denied for user '<a href="" class="__cf_email__" data-cfemail="6715080813270b0804060b0f081413">[email protected]</a>' (using password:NO)

After this I try:

mysql -u root -p

However, it asks for a password which I don’t have.

Update: as Bozho suggested, I did the following:

  1. I stopped the MySQL Service from Windows services
  2. Opened CMD
  3. Changed the location to c:program filesmysqlbin
  4. Executed the command below

    mysqld --defaults-file="C:\program files\mysql\mysql server 5.1\my.ini" --init-files=C:\root.txt

  5. The command ran with a warning about character set which I mentioned below
  6. I start the MySQL service from Windows services
  7. I write in the command line

    mysql -u root -p
    EnterPassword: 123 // 123 was the password

  8. The command line shows the following error

    Access denied for user '[email protected]' (using password:**YES**)

How do I solve this? I’m waiting to hear from you.

Method 1

for this kind of error; you just have to set new password to the root user as an admin. follow the steps as follows:

[root ~]# mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password:NO)
  1. Stop the service/daemon of mysql running
     [root ~]# service mysql stop   
     mysql stop/waiting
  2. Start mysql without any privileges using the following option;
    This option is used to boot up and do not use the privilege system of MySQL.
     [root ~]# mysqld_safe --skip-grant-tables &

At this moment, the terminal will seem to halt. Let that be, and use new terminal for next steps.

  1. enter the mysql command prompt
     [root ~]# mysql -u root
  2. Fix the permission setting of the root user ;
     mysql> use mysql;
     Database changed
     mysql> select * from  user;
     Empty set (0.00 sec)
     mysql> truncate table user;
     Query OK, 0 rows affected (0.00 sec)
     mysql> flush privileges;
     Query OK, 0 rows affected (0.01 sec)
     mysql> grant all privileges on *.* to <a href="" class="__cf_email__" data-cfemail="43312c2c37032f2c20222f2b2c3037">[email protected]</a> identified by 'YourNewPassword' with grant option;
     Query OK, 0 rows affected (0.01 sec)

*if you don`t want any password or rather an empty password

    mysql> grant all privileges on *.* to <a href="" class="__cf_email__" data-cfemail="a8dac7c7dce8c4c7cbc9c4c0c7dbdc">[email protected]</a> identified by '' with grant option;
    Query OK, 0 rows affected (0.01 sec)*
    mysql> flush privileges;
    Query OK, 0 rows affected (0.00 sec)

Confirm the results:

    mysql> select host, user from user;
| host      | user |
| localhost | root |
1 row in set (0.00 sec)
  1. Exit the shell and restart mysql in normal mode.
     mysql> quit;
     [root ~]# kill -KILL [PID of mysqld_safe]
     [root ~]# kill -KILL [PID of mysqld]
     [root ~]# service mysql start
  2. Now you can successfully login as root user with the password you set
      [root ~]# mysql -u root -pYourNewPassword 

Method 2

You can reset your root password. Have in mind that it is not advisable to use root without password.

Method 3

1) You can set root password by invoking MySQL console. It is located in

C:wampbinmysqlmysql5.1.53bin by default.

Get to the directory and type MySQL. then set the password as follows..

    > SET PASSWORD FOR <a href="" class="__cf_email__" data-cfemail="42302d2d36022e2d21232e2a2d3136">[email protected]</a> = PASSWORD('new-password');

2) You can configure wamp’s phpmyadmin application for root user by editing

Note :- if you are using xampp then , file will be located at

It looks like this:

        $cfg['Servers'][$i]['verbose'] = 'localhost';
        $cfg['Servers'][$i]['host'] = 'localhost';
        $cfg['Servers'][$i]['port'] = '';
        $cfg['Servers'][$i]['socket'] = '';
        $cfg['Servers'][$i]['connect_type'] = 'tcp';
        $cfg['Servers'][$i]['extension'] = 'mysqli';
        $cfg['Servers'][$i]['auth_type'] = 'config';
        $cfg['Servers'][$i]['user'] = 'root';
        $cfg['Servers'][$i]['password'] = 'YOURPASSWORD';
        $cfg['Servers'][$i]['AllowNoPassword'] = false;

The error “Access denied for user ‘[email protected]’ (using password:NO)”
will be resolved when you set $cfg['Servers'][$i]['AllowNoPassword'] to false

If you priviously changed the password for ‘[email protected]’, then you have to do 2 things to solve the error “Access denided for user ‘[email protected]‘”:

  1. if [‘password’] have a empty quotes like ‘ ‘ then put your password between quotes.
  2. change the (using password:NO) to (using password:YES)

This will resolve the error.

Note: phpmyadmin is a separate tool which comes with wamp.
It just provide a interface to MySQL. if you change my sql root’s password, then you should change the phpmyadmin configurations. Usually phpmyadmin is configured to root user.

Method 4

Use mysql -u root -p
It will ask for password, insert password and enter.

Method 5

I was getting the same error on OS X El captain.
Mysql version 5.7 . I was able to connect to mysql with root after executing these steps.

Stop the mysql server

sudo mysql.server stop

Start mysql in safe mode

sudo mysqld_safe --skip-grant-tables

Using mysqld, Change the database to mysql and update the details for user ‘root’.

show databases;
use mysql;
UPDATE mysql.user 
    SET authentication_string = PASSWORD('MyNewPass'), password_expired = 'N'
    WHERE User = 'root' AND Host = 'localhost';

After that kill the ‘mysqld_safe’ process and start mysql normally. You should be able to login to mysql using root and new password. SQL docs for more details

Method 6

Simply edit my.ini file in C:xamppmysqlbin path. Just add:


line in between lines of # The MySQL server [mysqld] and port=3306. Then restart the MySQL server.

Looks like:


Method 7

Make sure the MySQL service is running on your machine, then follow the instructions from MySQL for initially setting up root (search for ‘windows’ and it will take you to the steps for setting up root):

Securing the Initial MySQL Account

Method 8

For some information I’ve get error after changing password:

Access denied for user ‘root’@’localhost’ (using password: NO)

Access denied for user ‘root’@’localhost’ (using password: YES)

In both cases there was error.

But the thing is after that I’ve tried it with

mysql -uroot -ppassword instead of

mysql -u root -p password -> with spaces between -uroot and -ppassword so maybe if someone get trouble can try this way.

Method 9

Another solution if someone gets the error The specified password for user account ‘root’ is not valid, or failed to connect to the database server also with the right password, is the follow

•In the Windows registry, delete the mysql_pwd reg key under HKCUSoftwareMicrosoftWebPlatformInstaller

•Unistall older version of MySQL .NET connector

•Download and install the latest MySql .NET Connector.

Method 10

For MySQL 5.7. These are the below steps:

Stop your MySQL server completely. This can be done by accessing the Services window inside Windows XP and Windows Server 2003, where you can stop the MySQL service.

Open your MS-DOS command prompt using “cmd” inside the Run window. Inside it navigate to your MySQL bin folder, such as C:MySQLbin using the cd command.

Execute the following command in the command prompt: mysqld.exe -u root –skip-grant-tables

Leave the current MS-DOS command prompt as it is, and open a new MS-DOS command prompt window.

Navigate to your MySQL bin folder, such as C:MySQLbin using the cd command.

Enter mysql and press enter.

You should now have the MySQL command prompt working. Type use mysql; so that we switch to the “mysql” database.

Execute the following command to update the password:

update user set authentication_string=password(‘1111′) where user=’root’;

Method 11

In your code replace the ‘root’ with your Server username and password with your server password.
For example if you have DB and your php files on the server
then obviously you would have to enter into this server site using your username and password.

Method 12

If you are using XAMPP just go to C:xamppphpMyAdmin and then open find $cfg['Servers'][$i]['password'] = '' line and put your password there.

Method 13

if you changed the port to non standard one, then you need to specify it:

$connection = mysqli_connect('localhost:3308', 'root', '', 'loginapp');

Method 14

Some times it just happens due to installation of Wamp or changing of password options of root user.
One can use privilages–>root (user) and then set password option to NO to run the things without any password OR set the password and use it in the application.

Method 15

  1. Change the password from present in C:xamppphpMyAdmin.
  2. Type mysql -u root -p in the command prompt.
  3. You will be asked to enter the password. Enter that password which you updated in the

Method 16

If the root account exists but has no password, connect to the server as root using no password, then assign a password. This was my situation when I encountered this issue.

Connect to the server as root using no password:

$> mysql -u root --skip-password

Assign a password:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'root-password';

I was able to solve my problem this way. Hope this helps someone who encounters a similar issue in the future. Cheers!


Method 17

mysqladmin -u root -p password

enter your current password


enter your new password

Method 18

It happens because of the security reason.

try with the following

mysql -u root -p

click enter and enter the password and try again
