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 wanna create new project, you have to specify the HOST name in the add remote origin step change.

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
