Herein, we report the first example of one-time password (OTP) generation and two-factor authentication (2FA) using a molecular approach. OTPs are passwords that are valid for one entry only. For the next login session, a new, different password is generated. This brings the advantage that any undesired recording of a password will not risk the security of the authentication process. Our molecular realization of the OTP generator is based on a photochromic molecular triad where the optical input required to set the triad to the fluorescent form differs depending on the initial isomeric state.
在此，我们报告了首例使用分子方法生成一次性密码（OTP）和进行双因素身份验证（2FA）的实例。一次性密码是仅对一次输入有效的密码。对于下一次登录会话，会生成一个新的、不同的密码。这带来的优势在于，任何对密码的不当记录都不会危及身份验证过程的安全性。我们对一次性密码生成器的分子实现基于一种光致变色分子三联体，其中将三联体设置为荧光形式所需的光输入因初始异构状态而异。
