Simple CLI tool
2fa is a lightweight command-line two-factor authentication tool that generates TOTP codes directly from the terminal, making it convenient for developers and power users who prefer working in the command line.
No phone dependency
By storing 2FA secrets on your computer, you eliminate the need to pull out your phone every time you need a TOTP code. This is especially useful when working at a desktop and logging into services frequently.
Easy integration with workflows
As a CLI tool, 2fa can be easily scripted and integrated into automated workflows, shell scripts, or combined with other command-line tools for streamlined authentication processes.
Minimal and focused
Written in Go by Russ Cox (a prominent Go team member), the tool is minimal, well-written, and does one thing well — generating time-based one-time passwords. It has very few dependencies and is easy to build and install.
Open source and auditable
The source code is publicly available on GitHub, allowing users to inspect, audit, and verify the security of the tool themselves, which is important for a security-sensitive application.
