docker-credential-helpers VS pass-otp

Docker supports a credential-helper module[0], which supports 4 different backends for fetching the docker registry credentials: osxkeychain, pass, wincred, and secretservice.

pass lets you use GPG-smartcards, and many of those (such as Yubikeys) will let you enforce touch-policies for signing/encruption.

As a combination of both these however, I must touch my Yubikey every time I pull a new docker image.

Another cool use-case is that I use the terraform-pass-provider to save secrets for my personal terraform project.

# Finds the latest version $ wincred_version=$(curl -fsSL -o /dev/null -w "%{url_effective}" https://github.com/docker/docker-credential-helpers/releases/latest) # Downloads and extracts the .exe $ sudo curl -fL \ "https://github.com/docker/docker-credential-helpers/releases/download/${wincred_version}/docker-credential-wincred-${wincred_version}-$(dpkg --print-architecture).zip" | zcat | sudo tee /usr/local/bin/docker-credential-wincred.exe >/dev/null # Assigns execution permission to it $ sudo chmod +x /usr/local/bin/docker-credential-wincred.exe

otp tokens are included in the encrypted file. It’s just appended to the file, e.g. otpauth://totp/… You’ll need to install https://github.com/tadfisher/pass-otp on desktop for this to work. But the android client comes with support builtin.

I use pass myself. I had no idea you could use it for otp. Are you using something like this? https://github.com/tadfisher/pass-otp

I use https://github.com/tadfisher/pass-otp with pass, which has a FOSS client for desktop and smartphone (at least for andriod, no idea for ios)

There are the password manager pass (https://www.passwordstore.org/), which has an extension pass-otp (https://github.com/tadfisher/pass-otp). This extension can be used instead of Google Authenticator.

> In particular, I don't see how 2FA is possible with this

Umm, why not?

First, you can use a different app (like aegis) to generate OTPs.

Second, pass has an extension (https://github.com/tadfisher/pass-otp) that can be used to generate OTPs.

git clone https://github.com/tadfisher/pass-otpcd pass-otpsudo make install

You can use pass
