otp-authenticator: OTP Authenticator (a la google) command line client

[ bsd3, cli, library, program, security ] [ Propose Tags ] [ Report a vulnerability ]

Simple tool for keeping track of your one-time pad two-factor authentication keys; basically a command-line version of the canonical google authenticator app.

The library uses GnuPG (through h-gpgme) to safely encrypt your secret keys. The first time you use it, it asks for a fingerprint to use for encryption. Currently GnuPG 1.x has some issues with h-gpgme when asking for keys, so GPG 2.x is recommended. Keys are stored, encrypted, at `~/.otp-auth.vault` by default.

otp-authenticator

Simple tool for keeping track of your one-time pad two-factor authentication keys; basically a command-line version of the canonical Google Authenticator App.

The library uses GnuPG (through h-gpgme) to safely encrypt your secret keys. The first time you use it, it asks for a fingerprint to use for encryption. Currently GnuPG 1.x has some issues with h-gpgme when asking for keys, so GPG 2.x is recommended. Keys are stored, encrypted, at ~/.otp-auth.vault by default.

Instructions are available through --help, but the basics are:

# interactively add a new key
otp-auth add

# interactively add a new key by entering the secret key uri
#   (following the otpauth protocol)
otp-auth add --uri

# view all time-based codes and cached counter-based codes
otp-auth view

# list accounts, do not display codes
otp-auth view --list

# generate a new counter-based code
otp-auth gen ID

# edit the metadata and delete codes
otp-auth edit ID
otp-auth delete ID

# dump all stored data as json (and as yaml)
otp-auth dump
otp-auth dump --yaml

You can edit configuration at ~/.otp-auth.yaml, the basic schema is:

fingerprint: ABCDEF12
vault: /home/robert/.otp-auth.vault
