Answer 1

Try change the password as below:

ALTER USER 'root'@'localhost' IDENTIFIED BY 'your new password'; 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your new password';

Answer 2

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password'; 
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

FLUSH PRIVILEGES;

"password" is that you have to change the password you already have or you will modify it for a new one
