There are different ways authentication can be used in FTP, including:
1. Basic authentication: This involves providing a username and password to connect to the FTP server. This is the most common way of authenticating with an FTP server.
1. SSL/TLS protection: FTP can be secured with SSL/TLS protocols, which offer secure, encrypted connections between the client and the server. This type of authentication protects against eavesdropping and man-in-the-middle attacks.
1. SSH/SFTP: SSH (Secure Shell) is a secure alternative to FTP that uses encrypted connections to transfer files. SFTP (SSH File Transfer Protocol) provides a secure method of file transfer over SSH connections with authentication based on public and private keys.
1. Active Directory integration: FTP servers can be integrated with an organization’s Active Directory (AD) to enable users to authenticate with their AD credentials. This offers centralized control and management of user accounts and permissions.
1. Biometric authentication: Some FTP clients and servers support biometric authentication methods, such as fingerprint scanning, which can provide an extra layer of security.
