Dynamic passwords are unpredictable random number combinations generated by a special algorithm. Each password can only be used once. The password is a one-way association sequence, and the system only records the nth password. When a user logs in using the n-1th password, the system uses a one-way algorithm to calculate that the nth password matches the nth password it has saved to determine the user's legitimacy. Because n is finite, the password sequence must be reinitialized after the user logs in n times.

2. As one of the most secure identity authentication technologies, dynamic passwords have been applied in more and more industries. The purpose of identity authentication is to identify the true identity of the communication counterparty and prevent forgery and impersonation. The technical method of identity authentication is mainly cryptography, including symmetric encryption algorithms, public key encryption algorithms, digital signature algorithms, etc.

3. SMS password is a dynamic password requesting 6 or more random numbers in the form of mobile phone text messages. The verification information of SMS verification code is very simple. Generally composed of four or six digits randomly. People who know how to access the Internet will naturally have no difficulty with such a simple verification.
