Some systems like Ubuntu  mysql is using by default the UNIX auth socket plugin  Basically means that  db users using it  will be  quot auth quot  by the system user credentias  You can see if your root user is set up like this by doing the following    sudo mysql -u root   I had to use  quot sudo quot  since is new installation  mysql gt  USE mysql  mysql gt  SELECT User  Host  plugin FROM mysql user    ------------------ -----------------------    User               plugin                   ------------------ -----------------------    root               auth socket               mysql sys          mysql native password     debian-sys-maint   mysql native password    ------------------ -----------------------   As you can see in the query  the root user is using the auth socket plugin There are 2 ways to solve this   You can set the root user to use the mysql native password plugin You can create a new db user with you system user  recommended   Option 1    sudo mysql -u root   I had to use  quot sudo quot  since is new installation  mysql gt  USE mysql  mysql gt  UPDATE user SET plugin  mysql native password  WHERE User  root   mysql gt  FLUSH PRIVILEGES  mysql gt  exit     sudo service mysql restart  Option 2   replace YOUR SYSTEM USER with the username you have    sudo mysql -u root   I had to use  quot sudo quot  since is new installation  mysql gt  USE mysql  mysql gt  CREATE USER  YOUR SYSTEM USER   localhost  IDENTIFIED BY  YOUR PASSWD   mysql gt  GRANT ALL PRIVILEGES ON     TO  YOUR SYSTEM USER   localhost   mysql gt  UPDATE user SET plugin  auth socket  WHERE User  YOUR SYSTEM USER   mysql gt  FLUSH PRIVILEGES  mysql gt  exit     sudo service mysql restart  Remember that if you use option  2 you ll have to connect to mysql as your system username  mysql -u YOUR SYSTEM USER  Note  On some systems  e g   Debian stretch   auth socket  plugin is called  unix socket   so the corresponding SQL command should be  UPDATE user SET plugin  unix socket  WHERE User  YOUR SYSTEM USER   Update  from  andy s comment seems that mysql 8 x x updated replaced the auth socket for caching sha2 password I don t have a system setup with mysql 8 x x to test this  however the steps above should help you to understand the issue  Here s the reply  One change as of MySQL 8 0 4 is that the new default authentication plugin is  caching sha2 password   The new  YOUR SYSTEM USER  will have this auth plugin and you can login from the bash shell now with  quot mysql -u YOUR SYSTEM USER -p quot  and provide the password for this user on the prompt  No need for the  quot UPDATE user SET plugin quot  step  For the 8 0 4 default auth plugin update see  https   mysqlserverteam com mysql-8-0-4-new-default-authentication-plugin-caching sha2 password

I have done the following steps to get rid of this issue  Login into the MySQL in your machine using  sudo mysql -p -u root  and hit the following queries  1  CREATE USER  jack   localhost  IDENTIFIED WITH mysql native password BY   lt  lt any password gt  gt     2  GRANT ALL PRIVILEGES ON     TO  jack   localhost    3  SELECT user plugin host FROM mysql user WHERE user    root    ------ ------------- -----------    user   plugin        host          ------ ------------- -----------     root   auth socket   localhost     ------ ------------- -----------   4  ALTER USER  root   localhost  IDENTIFIED WITH mysql native password BY   lt  lt any password gt  gt     5  FLUSH PRIVILEGES   Please try it once if you are still getting the error  I hope this code will help you a lot

I was having this issue on an Debian 8 VM that I was interacting with through Putty on my Windows 10 desktop   I tried the various suggestions on here but nothing quite worked and I am running MariaDB on the Debian host   In the end I found that I couldn t start the db server in safe mode but I didn t need to and the following commands actually worked for me i e  allowing a newly created MySql user to log into the MySql MariaDB server   sudo service mysql restart sudo mysql   logs in automatically into MariaDB use mysql  update user set plugin    where user  your user name   flush privileges  exit  sudo service mysql restart   restarts the mysql service   If the above doesn t quite work for you  follow the steps outlined in zetacu s post above  zetacu  then follow my steps   Now you should be able to use a remote terminal client and securely log into mysql using the command   mysql -u your user name -p    type in the password when prompted

I would suggest to remove the Mysql connection -  UPDATE-This is for Mysql version 5 5 if your version is different  please change the first line accordingly  sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5 5 mysql-client-core-5 5 sudo rm -rf  etc mysql  var lib mysql sudo apt-get autoremove sudo apt-get autoclean   And Install Again But this time set a root password yourself  This will save a lot of effort   sudo apt-get update sudo apt-get install mysql-server

After hours of struggle with no solution here  this worked for me then I found a youtube video where it says the password column is now called authentication string   So I was able to change my password as follows  First get into mysql from terminal  sudo mysql   then inside mysql type whatever after mysql    mysql gt  use mysql mysql gt  update user set authentication string PASSWORD  mypass   where user  root   mysql gt  flush privileges  mysql gt  quit    at this point you are out of mysql back to your normal terminal place  You need to restart mysql for this to take effect  for that type the following   sudo service mysql restart   Refer to this video link for better understanding

I found my solution after hours of research here   Stop MySQL  sudo service mysql stop   Make MySQL service directory   sudo mkdir  var run mysqld   Give MySQL user permission to write to the service directory   sudo chown mysql   var run mysqld   Start MySQL manually  without permission checks or networking   sudo mysqld safe --skip-grant-tables --skip-networking  amp    Log in without a password    mysql -uroot mysql   update password  UPDATE mysql user SET authentication string PASSWORD  YOURNEWPASSWORD    plugin  mysql native password  WHERE User  root  AND Host      EXIT    Turn off MySQL   sudo mysqladmin -S  var run mysqld mysqld sock shutdown   Start the MySQL service normally   sudo service mysql start

Check here   NEW Version of MYSQL does it this way   In the new my-sql if the password is left empty while installing then it is based on the auth socket plugin   The correct way is to login to my-sql with sudo privilege     sudo mysql -u root -p   And then updating the password using     ALTER USER  root   localhost  IDENTIFIED WITH mysql native password BY  new-password     Once this is done stop and start the mysql server      sudo service mysql stop    sudo service mysql start   For complete details you can refer to this link   Do comment for any doubt

You want to access MySQL with root user but you re not providing root s correct password   If you need to set a new password for root  MySQL s site has great documentation on how to do it  http   dev mysql com doc refman 5 7 en resetting-permissions html  I ll not show the process in here because MySql documentation on the above link it s clear and concise

This has happened to me as well  The problem is with the mysql repo that comes already with the linux distro  So when you simply do    sudo apt install mysql-server  it installs mysql from their default repo which gives this problem  So to overcome that you need to uninstall that installed mysql    sudo apt remove mysql  --purge --auto-remove  Then download mysql repo from official mysql website MySQL APT Repo  Follow their documentation on how to add repo and install it  This gives no issue  Also as answered by  zetacu  you can verify that mysql root now indeed uses mysql native password plugin

No need of sudo  The database is initialised with 2 all-privilege accounts  the first one is  root  which is inaccessible and the second one with your user name  check with command whoami    To enable access to root account  you need to login with your user name  mysql -u   whoami    and manually change password for root  use mysql  set password for  root   localhost    password  YOUR ROOT PASSWORD HERE    flush privileges  quit   Login as  root   mysql -u root -p
