    Tek kullanımlık şifre

    Kripto Sistemi

    Yazeka

    Arama sonuçlarına dayanarak oluşturuldu

    Tek kullanımlık şifre (OTP), dijital işlemlerde kimlik doğrulama için kullanılan ve yalnızca bir kez geçerli olan paroladır. Kripto sistemlerinde, hesaplara yetkisiz erişimi önlemek amacıyla mobil uygulamalar veya SMS ile gönderilir.12

    Zaman tabanlı (TOTP) ve HMAC tabanlı (HOTP) gibi türleri bulunur. TOTP, belirli aralıklarla değişen dinamik kodlar üretirken, HOTP her kullanımda artan sayaçla benzersiz parola oluşturur.23

    Kripto borsalarında ve cüzdanlarda yaygın kullanılır. Google Authenticator gibi uygulamalarla entegre çalışarak ek güvenlik sağlar.34
