py_oathtool2 is a Python script for easy OTP code generation on the command line for use with scripting or simply as a convenience. It is a maintained fork of https://github.com/matalo33/py_oathtool.
pip install py_oathtool2
py_oathtool2 automatically copies codes to the clipboard. This depends on the following programs being installed:
- Linux with X11:
xclip - Linux with Wayland:
wl-copy - MacOS:
pbcopy(installed by default)
Two pieces of information are required for each account:
- An account name / label
- Your 64 character oath secret provided by the 3rd party. This is typically a QR code, but websites often also offer the string.
The script will read these values from a config file sourced from, by default, ~/.otp-secrets.yaml in the following format:
otpsecrets:
github: IOOVV6U5AUHUISZKJNVCCG4JWUR5XDFSI7ND62A7QT5ZOEVYVA7JEEDKTG3ZM57B
aws-account-dev: XQYNZOIA4PWCTJCB9654EQP5LUIP23BOW6J5ZIRZZSDHK24AUEDUSCONP3KQQY4N
aws-account-prod: 57QPXJFJ4D2ILQBRZGSHKAZCJ2Y46C52FGVSZRYMY7UMWTIQI6I3GOJQZ4VJN2R4
Additionally, the following configuration options are supported in the ~/.otp-secrets.yaml file:
holdoff: Specify a different holdoff value to wait for the next codeuse_clipboard: Disable putting the code on the clipboard
List all configured accounts with -l:
$ otp -l
github
aws-account-dev
aws-account-prod
Generate an OTP by providing the account name. The script will provide the OTP code and also put it on the clipboard:
$ otp aws-account-dev
129987 (10sec)
See all arguments with:
$ otp --help
Autocompletion support can be added through use of the -t or -l flags. The former space-delimits accounts and the latter by newlines.
For zsh support, add the following to your .zshrc file:
compdef _otp otp
_otp() {
compadd `otp -t`
}
For fish support, add the following to your config.fish:
complete --command otp --no-files --arguments "(otp -l)"
After cloning use pipenv to install dependencies and run the script:
pipenv install --dev
pipenv run python src/py_oathtool2/otp.py [args]
pipenv run python -m unittest test/test_otp.py
pipenv run python -m build
pip install --force-reinstall dist/py_oathtool2-*.whl
rm dist/*
pipenv run python -m build
pipenv run python -m twine upload --config-file ~/.pypirc dist/*
Two factor auth is meant to provide an extra layer of account security and this tool does not exactly promote that concept. You are responsible for taking reasonable steps to protect your secrets file to prevent loss of secrets, and perhaps this is not the ideal two factor solution for your most important accounts.
