Two-Factor Authentication (2FA)

Glossary

What is Two-Factor Authentication (2FA)?

As a security mechanism, two-factor authentication (2FA) asks users to confirm their identity with two different pieces of identification.

Usually, this combines the user’s knowledge (like a password) with their possessions (such as a security token or smartphone). Through the addition of an additional security layer, 2FA greatly improves online account protection and lowers the risk of unauthorised access.

Common methods of 2FA include receiving a one-time code via SMS, using an authenticator app that generates time-based passwords, or employing hardware tokens that produce authentication codes. As an additional factor, biometric methods like fingerprint or facial recognition are also employed. Choosing a preferred method, gaining access to the online service’s security settings, and completing the setup instructions are all necessary to enable 2FA. Protecting sensitive data and adhering to industry rules require this extra security measure.

Why is Activating Two-Factor Authentication (2FA) Crucial?

  1. Enhanced Security: 2FA adds a layer of security beyond just a password. Even if a password is compromised, the second factor significantly reduces the risk of unauthorised access.
  2. Protection Against Phishing: Phishing attempts frequently deceive victims into disclosing their passwords. Even if an attacker manages to obtain the password, they cannot access the account without the second authentication factor when utilising 2FA.
  3. Defence Against Data Breaches: In the event of a data breach where passwords are exposed, 2FA provides an extra barrier that makes it much harder for attackers to exploit the stolen information.
  4. Compliance with Regulations: Many industries and regulatory frameworks require the use of 2FA to protect sensitive data, ensuring that organisations comply with security standards and avoid potential penalties.
  5. Safeguarding Personal Information: Sensitive information, including financial data, private correspondence, and documents, is frequently found in personal accounts. 2FA aids in preventing unauthorised parties from accessing this data.

Common 2FA Methods

  1. SMS-Based 2FA: The user receives a one-time code via SMS to their mobile number after entering the password, which they must enter to gain access.
  2. Authenticator Apps: Applications like Google Authenticator, Authy, or Microsoft Authenticator generate time-based one-time passwords (TOTP) that the user must key in in addition to their password.
  3. Email-Based 2FA: Similar to SMS, a one-time code is sent to the user’s registered email address, which must be entered to conclude the login process.
  4. Hardware Tokens: Physical devices like YubiKey generate or store authentication codes. The user connects the hardware token to their computer or mobile device to authenticate.
  5. Biometric 2FA: Uses biometric data such as fingerprints, facial recognition, or retina scans as an additional authentication factor.
