📌 Multi-Factor Authentication (MFA) Summary
Multi-Factor Authentication (MFA) is a security process that requires users to provide two or more independent credentials to verify their identity. These credentials typically fall into categories such as something you know, like a password, something you have, such as a phone or security token, and something you are, like a fingerprint or facial recognition. By combining multiple factors, MFA makes it much harder for unauthorised users to gain access to an account or system, even if one factor has been compromised.
🙋🏻♂️ Explain Multi-Factor Authentication (MFA) Simply
Think of MFA as locking your house with both a key and a code. Even if someone finds your key, they still need to know the code to get inside. It is an extra step, but it helps keep your important information safe.
📅 How Can it be used?
Add MFA to a web application so users must enter both a password and a code sent to their mobile phone.
🗺️ Real World Examples
A bank uses MFA for online banking. After entering their password, customers receive a temporary code by text message, which they must enter before accessing their account. This extra step helps prevent fraud if a password is stolen.
A workplace requires employees to use MFA when logging in remotely. Staff must enter their password and then approve the sign-in request using an authentication app on their mobile device, reducing the risk of unauthorised access.
✅ FAQ
What is Multi-Factor Authentication and why should I use it?
Multi-Factor Authentication, or MFA, is a way to make your online accounts much more secure. It works by asking for two or more pieces of information before you can log in, such as a password and a code sent to your phone. Even if someone figures out your password, they still need the other piece of information, which makes it much harder for anyone else to get into your account.
How does Multi-Factor Authentication actually work when I log in?
When you log in with MFA turned on, you first enter your usual password. Then, you are asked for something else, like a code from a text message or an app, or even your fingerprint. This extra step helps make sure it really is you trying to access your account, not someone who has just guessed or stolen your password.
Is Multi-Factor Authentication difficult or inconvenient to use?
While MFA does add a step to your login process, most people find it quick and simple after a few tries. The extra security it gives is well worth the few extra seconds it takes. Many apps and websites make it easy to set up, and you only need to do the extra step when logging in from a new device or after a certain period of time.

Graph-Based Prediction
Graph-based prediction is a method of using data that is organised as networks or graphs to forecast outcomes or relationships. In these graphs, items like people, places, or things are represented as nodes, and the connections between them are called edges. This approach helps uncover patterns or make predictions by analysing how nodes are linked and how information flows through the network. It is especially useful when relationships between items are as important as the items themselves, such as in social networks or recommendation systems.
Statechain Protocols
Statechain protocols are a type of cryptographic technology designed to transfer ownership of digital assets, such as Bitcoin, without moving them on the public blockchain. Instead, control over the asset is passed between parties using a secure chain of signatures and encrypted messages, which are verified by a trusted server called a statechain entity. This approach allows for quicker and cheaper transactions by reducing the need for on-chain activity, while still maintaining security and privacy.
Secure File Transfer
Secure file transfer is the process of sending files from one device or location to another while keeping the data safe from unauthorised access. This is usually achieved using encryption and authentication methods that protect the information both while it is being sent and when it is stored. Secure file transfer helps organisations and individuals keep private or sensitive files safe when sharing them over the internet or private networks.
Low-Code Platforms for Business Users
Low-code platforms for business users are software tools that allow people with little or no coding experience to build applications using visual interfaces and simple logic. These platforms use drag-and-drop features and pre-built templates to help users create apps quickly and efficiently. They reduce the need for traditional programming, making it easier for business teams to solve problems and automate tasks themselves.
Human Resource Management
Human Resource Management (HRM) is the process of hiring, training, and supporting employees within an organisation. It involves managing everything related to a companynulls staff, including recruitment, payroll, benefits, and workplace policies. The goal of HRM is to help employees do their best work while ensuring the company meets its business objectives.
