I got a solution   When resetting root password at step 2   also change the auth plugin to mysql native password   use mysql  update user set authentication string PASSWORD     where User  root   update user set plugin  mysql native password  where User  root      THIS LINE  flush privileges  quit    This allowed me to log in successfully     Full code solution  1  run bash commands  1  first  run these bash commands  sudo  etc init d mysql stop   stop mysql service sudo mysqld safe --skip-grant-tables  amp    start mysql without password   enter - gt  go mysql -uroot   connect to mysql   2  then run mysql commands    copy paste this to cli manually  use mysql    use mysql table update user set authentication string PASSWORD     where User  root     update password to nothing update user set plugin  mysql native password  where User  root     set password resolving to default mechanism for root user  flush privileges  quit    3  run more bash commands  sudo  etc init d mysql stop  sudo  etc init d mysql start   reset mysql   try login to database  just press enter at password prompt because your password is now blank mysql -u root -p    4  Socket issue  from your comments   When you see a socket error  a community came with 2 possible solutions   sudo mkdir -p  var run mysqld  sudo chown mysql  var run mysqld sudo mysqld safe --skip-grant-tables  amp     thanks to  Cerin   Or      mkdir -p  var run mysqld  amp  amp  chown mysql mysql  var run mysqld      thanks to  Peter Dvukhrechensky     Blind paths and possible edge errors  Use 127 0 0 1 instead of localhost  mysql -uroot    -hlocalhost  is default   Can lead to  missing file  or slt error   mysql -uroot -h127 0 0 1   Works better   Skip the socket issue  I ve found many ways to create mysqld sock file  change access rights or symlink it  It was not the issue after all   Skip the my cnf file  The issue also was not there  If you are not sure  this might help you

The mysql command by default uses UNIX sockets to connect to MySQL   If you re using MariaDB  you need to load the Unix Socket Authentication Plugin on the server side   You can do it by editing the  mysqld  configuration like this    mysqld  plugin-load-add   auth socket so   Depending on distribution  the config file is usually located at  etc mysql  or  usr local etc mysql

In case someone lands here after making the same mistake I did    Switched to plugin  mysql native password  temporarily  Performed my tasks  Attempted to switch back to the  auth socket  plugin  but incorrectly referenced it as plugin  auth socket  which resulted in mysql  ERROR 1524  HY000   Plugin  auth socket  is not loaded  Lacking a way to login to fix this mistake  I was forced to have to stop mysql and use mysql safe to bypass authentication in order to switch to the appropriate plugin plugin  unix socket    Hopefully this saves someone some time if they receive the original poster s error message  but the true cause was flubbing the plugin name  not actually lacking the existence of the  auth socket  plugin itself  which according to the MariaDB documentation       In MariaDB 10 4 3 and later  the unix socket authentication plugin is installed by default  and it is used by the  root   localhost  user account by default
