Dynamic Password is also known as One Time Password. It is used to solve the traditional problems which occur when the static Password authentication cannot cope with eavesdropping and replaying, making, guessing, etc.
Using dynamic password, uncertainties will be treated in authentication information during the procedure of lodging to make authentication information different every time, which can enhance the security of information in the procedure of lodging. This technology can effectively prevent replay attack, and solve the issues that the static password is likely to be stolen in transmission and database.
There are three fields which are transmitted to authentication server or KDC. Those are Principal ID, Principal Password & current system timestamp of user‘s device. Principal password & timestamp are hashed first & then sent.
In server side, server checks to view that user is the right one or not who it assume to be. Server has its database of authentic Principal ID & Principal Password pairs. Server firstly verify for replay attack by comparing the timestamps. Then server checks to view a right password is supplied or not by comparing hash values of received & server generated values. The next process is generation of secret key used to encrypt the ticket.
The dynamic password method enhance traditional password approaches by using the processing capability of smart cards for making a multiple password for each authentication attempt. The smart card creates new passcodes several times a day. The host implements the same algorithm as the smart card, therefore it knows the password token's current valid password at any given time.
The card issuer boot up each card in the system with a synchronization procedure that loads an initialization code, or seed, into both the password token and host. The seed and the algorithm for deciding the passwords are kept secret. The seed value and initialization code for each card are unique such that no two cards must have the same password at a given time. It is unlikely that someone can predict the valid password at any given time without understanding the algorithm, seed, and initialization value.
During authentication, the password token shows the current password, which is sent to the host. The verifier compares the password received to the normal value. The host accepts the card if the identifiers connect. This method provides card authenticity, due to the lifetime of each password is short and the algorithm is variable with each card and maintain secret.
This approach implements authentication without using a CAD. Rather than, the user enters data (i.e., card identity number and password) into a computer terminal enabling remote log in. Smart cards used for this authentication method needed a battery, a display, and sometimes a keypad.
A dynamic password can simply be defined as a type of password that constantly changes, thus providing a high level of security against internal and external threats. A dynamic password doesn't mean users change their passwords all the time.

Password-based authentication is a method that requires the user to enter their credentials — username and password — in order to confirm their identity. Once credentials are entered, they are compared against the stored credentials in the system's database, and the user is only granted access if the credentials match.
However, static KBA is less secure because the questions often rely on publicly available information. On the other hand, dynamic knowledge-based authentication is more secure than the static method because the questions are tailored to the individual user, making it more difficult for an attacker to guess the answers.
Dynamic authorization uses attribute-based access control (ABAC) to provide a much more nuanced authorization service. Instead of relying solely on static permissions and role assignments to protect your resources, you configure policies that can take all kinds of attributes into account.
Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters. To protect yourself you need to create strong passwords that include a combination of all possible options.
One notable example of effective username and password authentication can be observed in the login system used by popular social media platforms such as Facebook. Facebook's login process employs a combination of a username or email address and a password to authenticate users and grant access to their accounts.
What is Password-Based Authentication? Password-Based Authentication is the process of gaining access to resources to which one is entitled with the help of a set of credentials containing a username and password.
There are three authentication factors that can be used: something you know, something you have, and something you are. Something you know would be a password, a PIN, or some other personal information.
Static authentication uses a specific authenticator, such as a password or PIN. It is called static because the authenticator is reused multiple times and stays the same until you change it. In contrast, in dynamic authentication a separate authenticator is generated for every session and nothing is ever reused.
Examples of dynamic KBA questions include: "What street address did you live on when you were 10 years old?" or "What color Ford Mustang was registered to you in New York state in 2002?" Although the answers to dynamic questions could be researched, it would take time.
A one-time password is impossible to reuse and is valid for just one-time use.Dynamic passwords change at regular intervals. RSA Security makes a synchronous token device called SecurID that generates a new token code every 60 seconds.

The dynamic password for online payment is a unique password for each payment, which the client receives via Bulbank Mobile (for individuals or legal entities) or Bulbank Online (for legal entities only) during the payment process online with a merchant participating in the secure payment programs VISA Secure and ...
The most popular types are complex passwords, passphrases, two-factor authentication, biometric authentication, and single-use passwords. Each type of password has its own benefits and can ensure that your information remains safe and secure.
