So  in case someone has the same situation and configuration as I had and is also about to go mad - this worked for me   After a long story I had a brew-installed MariaDB which kept automatically restarting when I killed its process  this was brew s doing   which had a root password  which I did not know     brew services list  This shows something like   mariadb started jdoe  path to homebrew mxcl mariadb plist  Stop the MySQL server with     brew services stop mariadb  Then start it again without the root user  and not using brew      mariadbd --skip-grant-tables  amp   Here  mysql secure installation did not work for me because of the --skip-grant-tables  and it would not work without the --skip-grant-tables because it needed the password  which I did not have   Trying   brew --prefix mysql  bin mysqladmin -u root password hunter2 only returned strange errors and did nothing    brew --prefix mariadb  bin mysqladmin -u root password hunter2 also didn t work  gave different errors  and suggestions that did not work for me    But you can log into mysql now without credentials    mysql  Here  the old method of updating the user table for root doesn t work because  Column  Password  is not updatable   The new method uses alter user BUT only works after you have done flush privileges  so do that first  Then  MariaDB   none   gt  alter user  root   localhost  identified by  hunter2    MariaDB   none   gt  is the MySQL prompt here  Then do flush privileges  again  Exit the MySQL client   Now as far as brew is concerned  MariaDB is still not running  and so use   ps aux   grep -i mariadb to find the pid and   kill -9  lt pid gt  it  Then use   brew services start mariadb to start it again

Since the question was asked answered long time ago  those top answers do not work for me  Here s my solution  in 2020   Background  Fresh mysql mariadb installed by homebrew   Problem  The password for root is not empty and unknown    The fix    mysql -u YOUR-SYSTEM-USERNAME -p The password is empty  press enter  ALTER USER  root   localhost  IDENTIFIED BY  NEW-ROOT-PASSWORD   FLUSH PRIVILEGES    The reason    Homebrew will create a user with root privileges named by the current MacOS username  it has no password Since it has all privileges  just reset the root password with that user  The initial password for root was randomly generated

Use init file to start mysql to change the root password   brew services stop mysql pkill mysqld echo  ALTER USER  root   localhost  IDENTIFIED BY  newRootPass     gt   tmp mysql-init   brew --prefix mysql  bin mysqld --init-file  tmp mysql-init   Your root password is now changed  Make sure to shutdown server properly to save password change  In new terminal window execute  mysqladmin -u root -p shutdown   and enter your new pass   Start your service and remove the init file  brew services start mysql rm  tmp mysql-init   Tested on mysql version 8 0 19

This worked for me for MAC https   flipdazed github io blog osx 20maintenance set-up-mysql-osx  Start mysql by running  brew services start mysql  Run the installation script  mysql secure installation  You will be asked to set up a setup VALIDATE PASSWORD plugin  Enter y to do this   Select the required password validation  Doesn   t really matter if it is just you using the database   Now select y for all the remaining options  Remove anon  users  disallow remote root logins  remove test database  reload privileges tables  Now you should receive a message of  All done

In case you have inadvertently set and forgot the root password  and you don t want to wipe all your databases and start over because you are lazy and forgot to have a back up solution in place  and you are using a fairly recent Homebrew install  Winter 2013   here are steps to reset your password for MySQL    Stop the currently running MySQL instance  launchctl unload -w   Library LaunchAgents homebrew mxcl mysql plist   Now start mysql by hand skipping the grant tables and networking    brew --prefix mysql  bin mysqld safe --skip-grant-tables --skip-networking   Note that if when you run echo   brew --prefix mysql  and it does not respond as   usr local opt mysql  in bash  you will need to adjust the path accordingly    Once you have done this  you now should have a running  unprotected MySQL instance up   Log in and set the password  mysql -u root   At the prompt  enter the following MySQL command to set a new password for the effected user    mysql gt  update mysql user set password PASSWORD  new password here   WHERE user  root     If all went to plan it should say    Query OK  1 row affected  0 02 sec  Rows matched  4  Changed  1  Warnings  0   Exit out of the MySQL prompt    mysql gt  exit Bye   Stop server   mysqladmin -u root shutdown   Now  lets put back the launch daemon so we have our MySQL at the ready again    launchctl load -w   Library LaunchAgents homebrew mxcl mysql plist   Congratulations  You ve just reset your mysql root password  Pour yourself a coffee and get a backup solution in place

I had this problem on a fresh install on Mac  I installed MariaDB with  brew install mariadb   Then started the service  brew services start mariadb  I was unable to run  mysql secure installation  as it prompted for the root password  Then I noticed in the install output  mysql install db --verbose --user jonny --basedir  usr local Cellar        So I tried logging in as the username specified in the mysql install db output and was successful e g  mysql -u jonny  Then at the mysql prompt if you want to set a password for the root user  SET PASSWORD FOR  root   localhost    PASSWORD  ToPsEcReT

Iam using Catalina and use this mysql secure installation command and now works for me     mysql secure installation NOTE  RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB       SERVERS IN PRODUCTION USE   PLEASE READ EACH STEP CAREFULLY   In order to log into MariaDB to secure it  we ll need the current password for the root user  If you ve just installed MariaDB  and haven t set the root password yet  you should just press enter here   Enter current password for root  enter for none    lt  lt  enter root here  gt  gt    i enter root as current password  OK  successfully used password  moving on     Setting the root password or using the unix socket ensures that nobody can log into the MariaDB root user without the proper authorisation    and do the rest

I ve just noticed something common to most of the answers here  and confirmed on my fresh install  It s actually obvious if you look at the recommendations to run mysqladmin -u root without -p   There is no password   Brew sets mysql up with just a root user and no password at all  This makes sense  I guess  but the post-install Caveats don t mention it at all

I had the same problem a couple days ago  It happens when you install mysql via homebrew and run the initialization script  mysql install db  before starting the mysql daemon   To fix it  you can delete mysql data files  restart the service and then run the initialization script   launchctl unload -w   Library LaunchAgents homebrew mxcl mysql plist rm -r  usr local var mysql  launchctl load -w   Library LaunchAgents homebrew mxcl mysql plist unset TMPDIR mysql install db --verbose --user  whoami  --basedir    brew --prefix mysql   --datadir  usr local var mysql --tmpdir  tmp
