The one-time password is copied to your clipboard automatically. You just need to paste it to the field on the website to confirm the correct setup and thus to activate the two-factor authentication.Securely Login to Website/Application From now on you will get asked for a one-time passwor...
SMS-based one-time passwords is a form of two-factor authentication. OTPs make it difficult to gain unauthorized access to restricted resources, like bank accounts or a databases with sensitive information. Static usernames and passwords can be accessed easily by an unauthorized intruder. By constan...
OTP全称叫One-time Password,也称动态口令,是根据专门的算法每隔30秒生成一个与时间相关的、不可预测的随机数字组合,每个口令只能使用一次,被认为是更安全的,因为密码不断变化,不容易受到重播攻击。 1.OTP类型 HOTP(HMAC-based One-Time Password的简写,表示基于HMAC算法加密的一次性密码):在RFC 4226中描述了它,该...

This method of logging in is called two-factor authentication (2FA), and it makes hacking much more difficult: stealing or guessing a password alone is no longer sufficient to hijack an account. But what should you do if you haven’t tried to log in anywhere yet suddenly receive a one-...
Static password authentication has security drawbacks. In two-factor authentication (2FA,) each user carries a device, called token, to generate passwords that are valid only one time. 2FA based on one-time passwords (OTPs) provides improved protection because users are prompted to provide something...
Two-Factor Authentication and One-Time Password 双因子认证(Two-Factor Authentication)认证是指结合密码以及实物(令牌、SMS等)两种条件对用户进行认证的方法,提高了系统的安全性。一次性密码(One-Time Passcode)是最为常用的双因子认证方法之一,如: HOTP: HMAC-Based One-Time Password ...
