You can configure a password policy, including policies on password expiration, reuse, and complexity, by configuring the following engine variables on all aggregator nodes - see the engine variables overview.
password_expiration_seconds: The time in seconds before a password expires. The default value is
0, which indicates that passwords will never expire.
expire_root_password: Specifies whether the root password can expire. The default value is
OFF. When set to
password_expiration_seconds duration does not apply to the root password. If set to
ON, the root password will expire after the
password_expiration_seconds duration is reached.
password_history_count: Restricts the reuse of previous user passwords. This variable is the number of previous passwords per user that MemSQL will store and disallow from reuse.
MemSQL will disallow setting a user account’s password to one of the last
password_history_count number of passwords for that user. The count includes the current password. For example, if set to
2, setting a user’s password to its current password or the last password before the current password is disallowed. The default value is
0, which indicates that any previous password can be reused. The maximum is
Password complexity requirements
strict_passwords: When set to
ON, MemSQL will require that all passwords be at least 6 characters in length, contain at least one letter, and contain at least one number. The default value is
