Putty allows users to log in to a multi-user system account from a Microsoft Windows PC, and it is a freely available open-source software emulator.

Simon Tatham created Putty in the C language for Microsoft Windows as a Telnet, rlogin, and SSH client that facilitates connections to the serial port.

Putty is a widely recognized client for SCP, SSH, TELNET, and rlogin on Windows, which allows remote access to servers via computers using the SSH protocol.

Unlike FTP clients, Putty utilizes distinct protocols and TCP ports. Specifically, Putty functions as an SSH client rather than an FTP client.

Putty is a safe and secure software that can be downloaded and used for free as it does not contain any malicious content. Additionally, it adheres to all the necessary security protocols and employs cryptography ciphers to ensure data security and integrity.
