![]() Luckily, GitHub now supports code signed by an SSH key! This means you can use 1Password's SSH agent functionality to sign your commits instead of relying on GPG (which has been troublesome in the past on macOS). IdentityAgent "~/Library/Group Containers/.1password/t/agent.sock"' > ~/.ssh/configĪnd to confirm that everything is working, you can run the following command to see if 1Password prompts you for authentication and if GitHub recognizes your key! ssh about signing my code? Run the following command (on macOS - for Linux and Windows you need to change the SSH Agent location) echo 'Host To accomplish this, I modified the pasted snippet from 1Password to only use the SSH agent for github connections using the git user. I do, however, work on some open source software from time to time which requires that I have an SSH key to authenticate with GitHub. No worries then, I have you covered! At work, we have some complex configurations and security rules that wouldn't allow me to store my SSH key in this manor. ![]() Note: what if I only want to use it for git and not my servers? Once you have done this successfully, you will see a screen that looks like this telling you how awesome you are. You can follow the directions and copy the snippet like in the screen below. Now, we must add a snippet of code to our SSH configuration file to tell the SSH command we wish to delegate key management to 1Password. Enable the SSH Agent and optionally biometrics if you wish. To enable this functionality, we need to tell 1Password that we are a developer which also enables fancy CLI options! Hit CMD +, or open the app settings in the way your OS supports and click "developer". Worry not, 1Password thought of this and provides a SshAgent to do our bidding (err, our authenticating at least). Ok you caught me, you have a fancy new key store but no way to actually use it to SSH into your servers or to clone a repository. Now you will click on the row in 1Password that says "public key" and copy it to your clipboard. Save your new key to your private vault and you are ready to go (well, almost. Most servers now days should work fine with Ed25519, the most modern and fastest standard, however. By default Ed25519 is used to generate the key but you may select RSA instead if you need that compatibility. Give it a good name, hit "add private key" and click "generate". Simply hit "New Item" and pick "SSH Key". What if I told you there is an easier way, using a tool that should already be in your back pocket? 1Password saves the day (key)ġPassword has a wonderful SSH key generation functionality built into the mobile and desktop versions. What happens if your laptop takes a bath or you decide that shiny M1 processor is worth an upgrade, though - you now need to go through a long process of restoring your backup (you have one, right?) or creating a new key and adding it to all of your services. For years this has been a standard and secure practice to access hosts over the internet by generating and storing a key on your local disk. ![]() Without going too far in depth, SSH keys can be thought of the same way as your home's front door key - you use something you have to prove that access should be granted. Most engineers will abide by these well established rules, but how many take it a step further and apply it to the software we create? This is where 1Password 8 comes in. We all know the best practices now that have been hammered into our heads: use a random password different for every website, use two-factor auth, use a password manager to encrypt your digital life, etc. With the ever evolving complexity of the internet, you may not even realize the amount of attack surface available to a bad actor. I also dabble in other projects, like home automation and helpful utilities to make my life a little bit easier. I have been hacking around on Android roughly since its creation: from kernel mods to app creation, I have done a little bit of it all. □ Hey there! I'm Simon, a senior Android engineer at Block.
