Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC 6238 .

2024年11月15日 · OATH time-based one-time password (TOTP) is an open standard that specifies how one-time password (OTP) codes are generated. OATH TOTP can be implemented using either software or hardware to generate the codes. Microsoft Entra ID doesn't support OATH HOTP, a different code generation standard.

Users can access an OTP for a given application or website through smartphone apps, a text message, or a proprietary token (such as a key fob). OneLogin Protect is an example of an OTP generator that you can use as an app on your phone.

2024年4月4日 · Time-based One-time Password (TOTP) is a widely adopted method for two-factor authentication. It generates unique, time-limited codes using a shared secret key and the current time. TOTP offers several advantages over SMS-based authentication, including offline capability, increased security, and privacy protection.

2018年6月18日 · By using the TOTP method, we are creating a one time password on the user side (instead of server side) through a smartphone application. This means that users always have access to their one time password. So it prevents the server from sending a text message every time user tries to login.

TOTP stands for Time-based One-Time Passwords and is a common form of two-factor authentication (2FA). Unique numeric passwords are generated with a standardized algorithm that uses the current time as an input.

2022年11月10日 · TOTP can be implemented in hardware and software tokens: • The TOTP hardware token is a physical keychain that displays the current code on a small screen • The TOTP soft token is a mobile application that displays a code on a phone’s screen

A time-based one-time password (TOTP) is a temporary passcode generated by an algorithm that uses the current time of day as one of its authentication factors. Time-based one-time passwords are commonly used for two-factor authentication and have seen growing adoption by cloud application providers. Why are TOTPs important?

Time-based One-Time Passwords (TOTPs) are temporary passcodes used to fortify the user authentication processes. They represent a dynamic and time-sensitive approach to verifying identity—a cornerstone of robust security strategies. So how do they work?

2022年12月4日 · TOTP stands for time-based one-time password (or passcode). A TOTP code is generated with an algorithm that uses a shared secret and the current time as inputs. This code is meant to grant users one-time access to an application. TOTP can be implemented in both hardware and software tokens:
