TMA-MYSQL-7.1

Ensure your authentication_policy is Set to a Secure Option

HochStufe 1Automatisiertmysql

Beschreibung

Define your authentication policy by setting the mysql system variable authentication_policy. The default value of authentication_policy is '*,,'. This means that factor 1 is required in account definitions and can use any authentication plugin (with caching_sha2_password being the default), and that factors 2 and 3 are optional and each can use any authentication plugin. Runs mysql -NBe with the client defaults: put an administrative account in ~/.my.cnf (mode 0600) or a mysql_config_editor login path, not MYSQL_PWD (see 1.4/1.6).

Set authentication_policy (e.g. '*,,' or 'caching_sha2_password,,') without mysql_native_password, then migrate accounts: SELECT user, host FROM mysql.user WHERE plugin = 'mysql_native_password'; ALTER USER <user> IDENTIFIED WITH caching_sha2_password BY RANDOM PASSWORD PASSWORD EXPIRE;
