Two Factor Authentication (2FA) solutions in 2022
19 Jun 2022
Two-Factor Authentication (2FA) is a security feature that requires two different factors to access your account. This includes something you know (a password), and something you have (your phone). 2FA is used to protect sensitive data like bank accounts, credit cards, social media accounts, etc.

2-factor Authentication (2FA)

2FA is a security measure that requires two different factors to complete an action. This is done to prevent unauthorized access to your account. In order to log into your account, you need to provide both something you know (your password), and something you have (a physical device).


Biometrics are a type of technology that uses physical characteristics or behavioral traits to identify individuals. They can be used to verify identity, track movement, and monitor access to secure areas.

Biometric Security

Biometrics are unique characteristics of your body that can be used to identify you. They include fingerprints, face recognition, iris scans, vein patterns, hand geometry, voice recognition, and even DNA. These biometric features can be used to verify your identity without requiring any other information.


Fingerprinting is a biometric method that has been around since the early 1900s. A fingerprint scanner reads the unique pattern of ridges and valleys on your finger pads. This information is then compared to a database of known prints. If the print matches, the individual is allowed entry.

Facial Recognition

Facial recognition is becoming increasingly popular due to its accuracy and convenience. In addition to verifying identity, facial recognition systems can be used to control access to buildings, computers, and even vehicles.

Typing Biometrics

Keystroke dynamics, keystroke biometrics, typing dynamics and typing biometrics refer to the detailed timing information that describes when each key was pressed and released as a person is typing on a computer keyboard.

Smart Contracts

Smart contracts are self-executing computer protocols that facilitate, verify, or enforce the negotiation or performance of a contract, or record transactions in a blockchain.

Smart Contracts Security

Smart contracts are computer programs that run on blockchain networks. They can be used to automate agreements between two parties safely and without needing third-party intermediaries. Smart contracts allow for trustless transactions, meaning they do not require a central authority to verify transactions. This means that smart contracts provide greater transparency than traditional methods of transaction verification.

Blockchain Technology

Blockchain technology has been around since 2009, but gained popularity in 2013 after Bitcoin was introduced. A blockchain is a public ledger of all transactions that have ever occurred on a network. It is decentralized and distributed across thousands of computers rather than being stored in a single location. Because of this, blockchains cannot be tampered with or hacked, making them ideal for financial applications.


Ethereum is a decentralized platform that runs smart contracts. It uses blockchain technology to facilitate the transfer of value from one party to another. To put simply, anyone who owns ether (the fuel that powers the Ethereum network) can write their own contract code. As long as someone accepts the terms of the contract, the code goes into effect. Once the contract is finished, the code automatically executes and the funds are transferred.
