One-time Password
A one-time password (OTP), also known as a one-time PIN, one-time authorization code (OTAC) or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device. OTPs avoid several shortcomings that are associated with traditional (static) password-based authentication; a number of implementations also incorporate two-factor authentication by ensuring that the one-time password requires access to ''something a person has'' (such as a small keyring fob device with the OTP calculator built into it, or a smartcard or specific cellphone) as well as ''something a person knows'' (such as a PIN). OTP generation algorithms typically make use of pseudorandomness or randomness to generate a shared key or seed, and cryptographic hash functions, which can be used to derive a value but are hard to reverse and therefore difficult for an attacker to obtain the data that was used for the hash. This is necessary because otherwise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Access Control
In computer security, general access control includes identification, authorization, authentication, access approval, and audit. A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access. Authentication and access control are often combined into a single operation, so that access is approved based on successful authentication, or based on an anonymous access token. Authentication methods and tokens include passwords, biometric scans, physical keys, electronic keys and devices, hidden paths, social barriers, and monitoring by humans and automated systems. Software entities In any access-control model, the entities that can perform actions on the system are called ''subjects'', and the entities representing resources to which access may need to be controlled are called ''objects'' (see also Access Control ...

Password Manager
A password manager is a computer program that allows users to store and manage their passwords for local applications and online services. In many cases software used to manage passwords allow also generate strong passwords and fill forms. Password manager can be delivered as a one of or mixed of: computer application, mobile application, web browser extension, web based service, portable software for USB units. A password manager assists in generating and retrieving complex passwords, storing such passwords in an encrypted database, or calculating them on demand. Depending on the type of password manager used and on the functionality offered by its developers, the encrypted database is either stored locally on the user's device or stored remotely through an online cloud storage. Password managers typically require a user to generate and remember one "master" password to unlock and access information stored in their databases. Modern password managers increase security usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KeePassXC
KeePassXC is a free and open-source password manager. It started as a community fork of KeePassX (itself a cross-platform port of KeePass). It is built using Qt5 libraries, making it a multi-platform application which can be run on Linux, Windows, macOS and BSD. KeePassXC uses the KeePass 2.x (.kdbx) password database format as the native format. It can also import (and convert) version 2 and the older KeePass 1 (.kdb) databases. KeePassXC supports having key files and YubiKey challenge-response for additional security. The Electronic Frontier Foundation mention KeePassXC as "an example of a password manager that is open-source and free." A secure code review of KeePassXC password manager version 2.7.4 was completed in late 2022. An accompanying browser extension is also available for Firefox, Google Chrome and Microsoft Edge.

YubiKey
The YubiKey is a hardware authentication device manufactured by Yubico to protect access to computers, networks, and online services that supports one-time passwords (OTP), public-key cryptography, and authentication, and the Universal 2nd Factor (U2F) and FIDO2 protocols developed by the FIDO Alliance. It allows users to securely log into their accounts by emitting one-time passwords or using a FIDO-based public/private key pair generated by the device. YubiKey also allows for storing static passwords for use at sites that do not support one-time passwords. Google, Amazon, Microsoft, Twitter, and Facebook use YubiKey devices to secure employee accounts as well as end user accounts. Some password managers support YubiKey. Yubico also manufactures the Security Key, a similar lower cost device with only FIDO2/WebAuthn and FIDO/U2F support. The YubiKey implements the HMAC-based One-time Password Algorithm (HOTP) and the Time-based One-time Password Algorithm (TOTP), and identifie ...

LastPass
LastPass is a password manager distributed in subscription form as well as a freemium model with limited functionality. The standard version of LastPass comes with a web interface, but also includes plugins for various web browsers and apps for many smartphones. It also includes support for bookmarklets. LogMeIn, Inc. (now GoTo) acquired LastPass in October 2015. On December 14, 2021, LogMeIn announced that LastPass would be made into a separate company and accelerate its release timeline. In 2022, LastPass suffered significant security incidents. User data, billing information, and vaults (with some fields encrypted and others not) were breached, leading many security professionals call for users to change all their passwords and switch to other password managers. Overview A user's content in LastPass, including passwords and secure notes, is protected by one master password. The content is synchronized to any device the user uses the LastPass software or app extensions on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Command-line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer (usual ...

Two-factor Authentication
Multi-factor authentication (MFA; encompassing two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something only the user knows), possession (something only the user has), and inherence (something only the user is). MFA protects user data—which may include personal identification or financial assets—from being accessed by an unauthorized third party that may have been able to discover, for example, a single password. A ''third-party authenticator'' (TPA) app enables two-factor authentication, usually by showing a randomly generated and frequently changing code to use for authentication. Factors Authentication takes place when someone tries to log into a computer resource (such as a network, device, or application). The resource requires the u ...
