Connect MySQL Workbench to WSL2

I have a brand new WSL2, running on the latest Windows 10 (2004) with Ubuntu 20.04, MySQL installed, I can access it from Bash and get the status --

mysql> status--------------mysql  Ver 8.0.20-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu))Connection id:          10Current database:Current user:           root@localhostSSL:                    Not in useCurrent pager:          stdoutUsing outfile:          ''Using delimiter:        ;Server version:         8.0.20-0ubuntu0.20.04.1 (Ubuntu)Protocol version:       10Connection:             Localhost via UNIX socketServer characterset:    utf8mb4Db     characterset:    utf8mb4Client characterset:    utf8mb4Conn.  characterset:    utf8mb4UNIX socket:            /var/run/mysqld/mysqld.sockBinary data as:         HexadecimalUptime:                 13 sec

Next I want to connect with MySQL Workbench.All I ever get is

Your connection failed for user 'root' to the MySQL server at 127.0.0.1:3306Access denied for user 'root'@'localhost'

My WSL2 list is ---

PS C:\Users\gymdo> wsl -l -v  NAME            STATE           VERSION* Ubuntu-20.04    Running         2

My WSL2 info is ---

Installation successful!To run a command as administrator (user "root"), use "sudo <command>".See "man sudo_root" for details.Welcome to Ubuntu 20.04 LTS (GNU/Linux 4.19.104-microsoft-standard x86_64) * Documentation:  https://help.ubuntu.com * Management:     https://landscape.canonical.com * Support:        https://ubuntu.com/advantage  System information as of Sat Jun 13 02:35:32 EDT 2020  System load:  1.97               Processes:             8  Usage of /:   0.4% of 250.98GB   Users logged in:       0  Memory usage: 0%                 IPv4 address for eth0: 172.20.109.28  Swap usage:   0%0 updates can be installed immediately.0 of these updates are security updates.

I have tried using the 172.20.109.28 from above --- same error

Looking at it from the Windows side with ---

I have tried using the 172.20.96.1 from above --- same error

One strange thing is --- when I try user name of root@localhost instead of simply root, the workbench pops up the "enter password" popup. So excited I was, but when I leave the password field blank it still fails with password: NO

I'm a beaten down man --- I need help.
