No reinstall needed for me,
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): << enter root here >>

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

mysql_secure_installation

it doesn't work for me :(

try :
sudo mysql_secure_installation

try :
sudo mysql_secure_installation

it working for me on Catalina 10.15.6

I did brew install mysql and then ran sudo mysql_secure_installation. The first thing it asks is the password for root. I've tried my login password, root, and no password and nothing and everything gives an Access denied for user 'root'@'localhost' error. It supposedly said it installed it without a password but not supplying one doesn't work. I've also tried mariadb and that doesn't work either. Can anyone help me get unstuck? Thanks!

Everytime I restart my system, I will have to re-do these steps to work with mysql! Is there a way I can make this a permanent change?
