This is a command-line authentication tool for natfrp, which is a tunneling service. Think of a tunnel as a secure connection that lets you access servers or services remotely. The tool handles the login process automatically so you don't have to enter credentials manually every time. When you run the tool, you give it three pieces of information: the address of your natfrp tunnel, your password, and optionally a TOTP secret (a code used for two-factor authentication, similar to what Google Authenticator uses). The tool then authenticates you with the tunnel service. If you want, it can save your authentication state locally so you stay logged in for future connections. The tool is written in Go, a programming language known for building small, fast command-line programs. You install it by downloading the code, compiling it on your computer, and then running it from your terminal with the appropriate flags for your tunnel address and credentials. Who would use this? Anyone who regularly connects to natfrp tunnels and wants to automate the authentication step. For example, if you're setting up a remote development environment, running a game server, or exposing a local application to the internet through natfrp, you'd use this tool instead of typing login details by hand each time. It's especially useful in automated scripts or server setups where manual login isn't practical. The README is fairly minimal and doesn't provide much context about what natfrp itself is or detailed examples, so if you're unfamiliar with tunneling services or two-factor authentication, you may need to read natfrp's own documentation to get the full picture.
