Pour la compatibilité avec tous les clients MySQL, il est recommandé de spécifier le mot de passe utilisateur avec double SHA1 dans le fichier de configuration. Si le mot de passe de l'utilisateur est spécifié SHA256, certains clients ne pourront pas s'authentifier (mysqljs et anciennes versions de l'outil de ligne de commande mysql).
