Starting from version 8.0.11, unlike mysql5.7 and previous versions, the default authentication method for setting a user's password is caching_sha2_password. If you find that the original program cannot connect to mysql after upgrading mysql8.0.11, you can quickly set it to mysql5.7 and previous versions of password authentication with the following command on the mysql command line client client. At the same time, the way to change the password under MYSQL8.0.11 is not the same as before. The original partial password change command cannot be used under mysql8.0.11.

Use mysql

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

FLUSH PRIVILEGES

The caching_sha2_password and sha256_password authentication plug-ins provide more secure password encryption than the mysql_native_password plug-in, and caching_sha2_password provides better performance sha256_password. Because of these superior security and performance features, caching_sha2_password is the preferred authentication plug-in for MySQL 8.0, and it is also the default authentication plug-in rather than mysql_native_password. This change will affect the server and libmysqlclient client libraries; currently, it is not compatible with frequently used client software.
