  • TOTP Authentication Tool

    From Onion Courier@21:1/5 to All on Wed Feb 19 19:40:00 2025
    Hi all,

    Maybe interesting for some of you, in case you
    have for example an Android device with Termux
    installed, or use already my minitalk program,
    with your PC, etc.

    $ totp -h

    Usage of totp:
    -account string
    The account name for the TOTP key (default "[email protected]")
    -issuer string
    The issuer for the TOTP key (default "example.com")
    -skew int
    The skew value for TOTP validation (default: 1) (default 1)

    $ totp

    TOTP Authentication Tool
    1. Generate a new shared secret
    2. Generate a passcode
    3. Validate a passcode
    4. Exit

    totp is updated, it supports now 8 digits passcodes and SHA256, SHA512.

    I tested the program with my Yubikey and the Yubikey Authenticator app
    and everything works fine.

    Added an option to generate deterministic shared secrets, because Bob
    travels a lot... ;-)
