What is 2FA Verification Code

2FA tool refers to software or services that implement two-factor authentication (2FA) functionality, mainly used to enhance account security. By combining passwords with physical verification (such as SMS verification codes, tokens, etc.), it prevents the risk of account theft with only passwords.

  • Two-factor authentication: Requires entering both password and received verification code (such as SMS, dynamically generated code from App). Even if the password is leaked, direct login is not possible.
  • Dynamic password: Refreshes every 60 seconds, generated by combining variables such as time and device, making it difficult to predict or crack.

Common 2FA Apps

Google Authenticator, Microsoft Authenticator
