rfa (Rust 2-Factor Authentication)

A blazing fast, minimalist command-line tool for managing and generating 2FA (TOTP) codes.

No electron apps, no cloud syncing, no bloated UI. Just your terminal and your TOTP tokens.

Installation

You can install rfa directly from crates.io (the package is named r2fa):

cargo install r2fa

(Note: Once installed, the command you type in your terminal is simply rfa)

2. Generate a 2FA code

To get the current 6-digit code for an account:

rfa <account_name>
