Double data security through two-factor authentication.

Double data security with two-factor authentication

Two-factor authentication otherwise known as 2FA is a type of multi-factor authentication (MFA) that requires two methods of identity confirmation. 2FA secures identity, data and applications. It protects against phishing, social engineering and brute-force attacks on passwords, and protects login data from attackers using weak or stolen credentials.

2FA is a fundamental element of the zero-trust security model. In order to access data, the user must confirm their identity.

What are the advantages of using 2FA

- protection of personal and business resources,
- there is no need to carry or download a token generator or associated application (for sprt solutions),
- most websites take advantage of mobile phone capabilities and send text messages to verify customer identity,
- password generators are more efficient than traditional passwords,
- generators are more secure as no two passwords are the same,
- makes it impossible for cybercriminals to hack and access data,
- are easy and user-friendly to manage,

Most popular authentication methods:

Hardware tokens

Has the appearance of a key fob that generates codes every few seconds to a minute.

Push notifications

Push does not require a password, it just sends a signal to the designated phone to approve, deny, accept or decline access to a website or app to verify identity.

SMS verification

SMS is sent to a designated, trusted phone number. The user is asked to use a one-time code to verify identity on the website or application.

Passwords

HMAC-based one-time password (HOTP) and time-based one-time password (TOTP). Both authentication methods generate temporary passwords from a physical device carried by the user. HOTP tokens expire after use, while TOTP tokens expire if not used within thirty seconds.

Voice authentication

Works similarly to push notifications, except that identity is confirmed automatically. The voice will ask you to press a key or provide your name to identify yourself.

Biometric authentication

This method usually uses a fingerprint or facial image, which must be shown to the smartphone camera.

Location-based

These confirm the user's identity based on his or her location in the world. The location factor is based on the IP address of the original user and compares the address with that of a new attempt to access the information.

Time

Authentication time factors verify identity through certain behaviours and the time it takes for a user to correctly log in to, for example, a computer. If an attempt is made outside the usual time frame, it may be challenged or terminated until, correct identity verification.

The demand for two-factor authentication has increased dramatically. The average cost of data breaches is now more than two trillion dollars per year.

The most common threats that 2FA protects against include:
- password theft or loss,
- phishing, emails sent by hackers to extract passwords,
- social engineering, a hacker impersonating and manipulating a person,
- Brute-Force Attacks hacker randomly generates passwords for a specific computer until they are in the correct sequence.
