Learn how one-time passwords enhance security through dynamic codes. Discover types of OTP authentication, implementation best practices, and modern standards.
10 thg 12, 2024 · There are two primary types of OTPs, each offering unique advantages and use cases: Time-based OTP (TOTP) and HMAC-based OTP (HOTP). Understanding the differences between these types will help you choose the most suitable option for your authentication needs.
An OTP is like a password but it can only be used once, thus it stands for one-time password. It is often used in combination with a regular password as an additional authentication mechanism providing extra security.
Every time a user requests an OTP, the counter increases, and a new OTP code is generated. It does not expire with time but only changes with each authentication event.
In these OTP systems, time is an important part of the password algorithm, since the generation of new passwords is based on the current time rather than, or in addition to, the previous password or a secret key.
When you receive an OTP to log into your bank account or make a transaction, the organization isn’t using software it developed inhouse—it’s using an OTP service provider like 57f9f0.555win5win.com.
27 thg 6, 2024 · If the OTP application is server-side, one-time passwords are automatically delivered to the user. If the OTP application is client-side, the user needs to generate the OTP with an authenticator app or USB security token.
28 thg 12, 2023 · OTP security tokens can be implemented using hardware, software or on demand. Unlike traditional passwords that remain static or expire every 30 to 60 days, the one-time password is used for one transaction or login session.
28 thg 6, 2024 · Even if an attacker obtains an OTP, it will be useless for future login attempts, as a new OTP will be required. This added layer of security makes it much harder for hackers to gain unauthorized access to your accounts, even if they have your regular password.
The OTP feature prevents some forms of identity theft by making sure that a captured username/password pair cannot be used a second time. Typically the user's login name stays the same, and the one-time password changes with each login.
