Overview

Public Key Authentication is a secure method for authentication, and how Aptible authenticates deployments initiated by pushing to an App’s Git Remote. You must provide a public SSH key to set up Public Key Authentication.

​

Supported SSH Key Types

Aptible supports the following SSH key types:

• ssh-rsa

• ssh-ed25519

• ssh-dss

​

Adding/Managing SSH Keys

If you don’t already have an SSH Public Key, generate a new SSH key using this command:

ssh-keygen -t ed25519 -C "your_email@example.com"

If you are using a legacy system that doesn’t support the Ed25519 algorithm, use the following:

shell ssh-keygen -t rsa -b 4096 -C "you@example.com"

Once you have generated your SSH key, follow these steps:

1. In the Aptible dashboard, select the Settings option on the bottom left.

2. Select the SSH Keys option under Account Settings.

3. Reconfirm your credentials by entering your password on the page that appears.

4. Follow the instructions for copying your Public SSH Key in Step 1 listed on the page.

5. Paste your Public SSH Key in the text box located in Step 2 listed on the page.
