هو صنف من أصناف معلومات أو بيانات الاعتماد التي تهدف إلى إثبات أن الشخص الذي يطلب الوصول إلى نظام أو مصدر ما هو بالفعل من يملك الإذن أو الحق بالوصول. تُعتبر كافة أنواع بيانات الاعتماد التي تنتمي إلى صنف محدد عنصر مصادقة واحد مستقل، فعلى سبيل المثال أسماء المستخدمين وكلمات المرور تنتمي إلى نفس النوع؛ لذلك تعتبر عنصر وحيد وتستخدم في أنظمة المصادقة الأحادية. تجمع أنظمة المصادقة متعددة العناصر بين عدة أنواع أو أصناف من عناصر المصادقة.
هناك خمس تصنيفات رئيسية لعناصر المصادقة هي:
