Two-Factor Authentication (2FA) is a security method used to help protect accounts and systems from unauthorized access by requiring users to complete an additional verification of their identity.

Verification Factors

A verification factor is a security method used to confirm the identity and authorization of a user before granting access to their account, allowing them to send communications, or request data from a secure network, system, or application.

What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a security process where users must provide two different authentication factors to verify their identity and access their account. This process provides stronger protection of a user’s personal information, credentials, and other assets, while also enhancing the security of the resources they can access.

It works by requiring two types of information from the user:

• The first factor

  is usually a password or a personal identification number (PIN).

• The second factor

  is typically a one-time code sent to the user’s phone.

2FA offers a higher level of security compared to methods that rely only on one factor (single-factor authentication), where the user provides just one element, such as a password or PIN.

This extra layer of security means that even if an unauthorized person knows a user’s password, they will not be able to access the user’s online account or mobile device.

What is a Two-Factor Verification Code?

A two-factor verification code is a one-time-use code sent to confirm a user’s identity when attempting to log in to an online account or system. The code is delivered via message, and once entered, the user gains access to their account.

These codes expire shortly after being issued if they are not used.

Benefits of Two-Factor Authentication

1. Adds an extra layer of security against attacks, strengthening the protection of systems and companies.

2. Protects against cyberattacks.

3. Reduces system security maintenance costs.
