• The first element: Information you know – usually login password.

• Second factor: Devices you own – such as smartphone, Authenticator App or physical security device (Security Token).

This authentication code is usually OTP code changes over time, which helps increase security and prevent unauthorized access, even if passwords are leaked.

Below is a summary of the most popular 2FA forms today, each method has its own advantages and disadvantages, suitable for each specific usage need.

3.1. SMS Authentication

SMS authentication method allows users to receive OTP (One-Time Password) code via text message each time they log in. After entering the password, you need to enter this OTP code to complete the authentication process.

• Advantage: Simple installation, easy to use, suitable for beginners.

• Disadvantages: OTP codes can be intercepted or stolen through attacks like SIM swapping, making the security level less than other methods.

Authentication applications such as Google Authenticator, Authy good Microsoft Authenticator will generate a one-time authentication code (TOTP) that changes automatically every 30 seconds. Users just need to open the app to get the verification code when logging in.

• Advantage: Higher security than SMS because the code is generated directly on the personal device, not transmitted over the network.

• Disadvantages: Requires app installation and management on separate devices, which can be inconvenient if the phone is lost.

3.3. Hardware Token

Hardware authentication devices such as YubiKey or U2 Fare physical security keys used to verify identity. They can connect to devices via USB, NFC, or Bluetooth.

• Advantage: Extremely high level of security, almost impossible to counterfeit or steal remotely.

• Disadvantages: Inconvenient if you travel frequently or don't want to carry extra equipment.

3.4. Biometric Authentication

Biometric authentication uses personal identifying characteristics such as fingerprint, face or iris to log into the system. This technology is increasingly popular on smartphones and personal computers.

• Advantage: Fast, convenient, no need to remember passwords or verification codes.

• Disadvantages: Not all devices support it, and security may depend on the quality of the hardware and recognition software.

3.5. Backup Codes

Backup codes are a set of one-time authentication codes, provided when you set up 2FA. Users should store these codes in a safe place for use in case they cannot access their primary authentication method (such as losing their phone or breaking their device).

• Advantage: Effective backup solution in case of emergency.

• Disadvantages: If not stored carefully, backup codes can be used by others without permission.
