Level 2 authentication, commonly known as Two-Factor Authentication (2FA), is a security measure designed to provide stricter account security protection than traditional usernames and passwords. By requiring users to provide two different types of authentication information, two-factor authentication ensures that even if one of the credentials (such as a password) is compromised, the account remains secure.
Biya Authenticator is a two-factor authentication tool used to enhance account security, similar to Google Authenticator or other two-factor authentication applications. It verifies the user’s identity by generating a one-time verification code, increasing account security.
