If you are trying to connect to a MySQL server from a text-based MySQL client from another computer  be it Docker or not   Most answers here involve connecting from a desktop client  or ask you to switch to an older authentication method  If you re connecting it with the MySQL client  text-based   I made it work with a Debian Buster in a Docker container   Say you have the apt system and wget set up  do the following    sudo apt-get update sudo apt-get install lsb-release -y Download a Debian package which update apt sources for you from the MySQL web site  sudo dpkg -i mysql-apt-config 0 8 13-1 all deb and select the options you want  In my case I only need MySQL Tools  amp  Connectors to be enabled  sudo apt-get update sudo apt-get install mysql-client -y Done  You can now run the new MySQL client and connect with the new authentication method

You can change the encryption of the user s password by altering the user with below Alter command       ALTER USER  username   ip address  IDENTIFIED WITH mysql native password BY    password     OR  We can avoid this error by make it work with old password plugin   First change the authentication plugin in my cnf file for Linux   my ini file in Windows       mysqld        default authentication plugin mysql native password   Restart the mysql server to take the changes in affect and try connecting via MySQL with any mysql client   If still unable to connect and getting the below error   Unable to load plugin  caching sha2 password    It means your user needs the above plugin  So try creating new user with create user or grant command after changing default plugin  then new user need the native plugin and you will able to connect MySQL   Thanks
