When you use MySQL V8 and tried to connect to the Database from Exploratory, you might see an error like below
Failed to connect to abcdefghijk
Error in .local(drv, ...) : Failed to connect to database: Error: Plugin caching_sha2_password could not be loaded: The specified module could not be found.
To workaround this, you can use mysql_native_password instead of the V8 default caching_sha2_password by executing SQL command below. (Replace <username> and <password> with your actual username and password)
ALTER USER '<username>' IDENTIFIED WITH mysql_native_password BY '<password>';
There is a stackoverflow question Authentication plugin ‘caching_sha2_password’ cannot be loaded that that you can check more details.
