User Password Security

GaussDB enhances user account security in the following aspects:

• User passwords are stored in the pg_authid system catalog. To prevent password leakage, GaussDB encrypts user passwords for storage. The encryption algorithm is determined by the password_encryption_type parameter. For details, see Setting Password Security Policies.
• All passwords must have a validity period. You can configure the password_effect_time parameter to set a validity period for each database user password, and configure password_notify_time to remind you to change a password.
