MULTIPLE PUBLIC SSH KEY ON YOUR MAC OSX

Create your ssh keys

First you need to create your two ssh key

$ ssh-keygen -t rsa -C "test1@test.com"
$ ssh-keygen -t rsa -f ~/.ssh/id_rsa_OTHER_LABEL -C "test2@test.com"

Note: You can use anyname for your public second key

Attach to github

login in each github account and attach your keys respectively. What do you gonna attach ?

$ vim ~/.ssh/id_rsa[YOUR_NAME].pub

copy and paste into the public key field at github page

Create a ssh config file

Well, we create two differents ssh keys and attach respectively in github. Now, we have to create a way to identify the differents github accounts.

Create a config file $ touch ~/.ssh/config $ vim ~/.ssh/config

example:

#Default GitHub
Host github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa
#Default GitHub
Host github-company
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_OTHER_LABEL

and save the changes.

How does it works?

Now, if you want to create a new project, you have to specify the HOST name in the add remote origin step.

Example $ git init $ git commit -m"firt commit" now if you use your first one ( normal github ) $ git remote add origin git@github.com:Company/testing.git instead it you want to use the other user just change the HOST name $ git remote add origin git@github-COMPANY:Company/testing.git
