Using multiple SSH accounts

I'm assuming you're familiar with git and it's trying to use SSH keys to access your repos and have multiple github accounts, lets say a personal a acc and a business acc.

Create ssh-key with your e-mail linked to your github account

ssh-keygen -t ed25519 -C "[email protected]"

Add the .pub key to your github>profile>ssh as a new authentication key

Copy the contents of your .pub file
Paste the contents and save

Copy the generated key and key.pub into your Windows/linux .ssh folder under your O.S user profile folder:

windows: %userprofile%/.ssh (if not exists, create the .ssh folder)
linux: ~/.ssh

Using multiple keys:

In order to use multiple accounts/keys you'll have to use "domain alias" to specify a target key.

A common clone command looks like: git clone [email protected]:[user_name]/[repo_name].git A "domain alias" is the @github.com after git.

Create a file or edit if exists on [filepath].ssh/config

The file name is "config" without extensions inside the .ssh folder.

Add the contents below:

# Comment to identify your account 1
Host github-acc-1
  HostName github.com
  User git
  IdentityFile ~/.ssh/[your key file name without .pub]
  IdentitiesOnly yes

# Comment to identify your account 2
Host github-acc-1
  HostName github.com
  User git
  IdentityFile ~/.ssh/[your key file name without .pub]
  IdentitiesOnly yes

Clone the repo using the domain alias replacing github.com with the acc you want to use

git clone git@github-acc-1:[user_name]/[repo_name].git
