As Indra said, avoid using root . This account should only be used by a human, even in a development environment. If you need an account that has complete and total access to everything, create one:

CREATE USER 'indra'@'localhost' IDENTIFIED WITH mysql_native_password BY 'superSecretPassword!123';
GRANT ALL ON *.* TO 'indra'@'localhost' WITH GRANT OPTION;

The root account in MySQL should only be used when you are configuring replication or fixing something what went really, really wrong
