Verlauf
Projektgeschichte und Nutzung
2fa is a command-line authentication-code generator for named TOTP and HOTP secrets.
Projektgeschichte
Russ Cox created 2fa as a compact command-line two-factor authentication agent written in Go. The project supports both time-based and counter-based one-time passwords and keeps its interface centered on adding, listing, and querying named keys.
Adoptionsgeschichte
The repository's focused scope and small codebase made 2fa a recognizable Unix-style authenticator among command-line users. Its official GitHub repository has accumulated substantial community interest, while the input records Homebrew distribution.
Wie es verwendet wird
Use `2fa -add name` to enroll a secret, `2fa -list` to list stored names, and `2fa name` to print a current code. With no arguments it prints codes for all time-based keys; `-clip` also copies a code to the clipboard.
Warum Paket-Nerds sich dafür interessieren
2fa exemplifies the small, composable command-line security tool: enrollment and code generation fit into scripts and terminal workflows. Package users should note its deliberate simplicity also means secrets are stored unencrypted in a plain text file.
Zeitleiste
- 2014: The earliest public repository history dates to the project's initial Go implementation.
- 2018: The repository's compact modern form added module metadata and vendored clipboard support.
Related projects
- The utility implements the TOTP and HOTP styles of one-time passwords and can optionally integrate with the system clipboard.
