multiple SSH keys for github (or bitbucket) accounts & SSH Config

If you are using multiple github account for work and home projects or you are using one github account and one bitbucket account or any other git hosting service out there with SSH you have to manage SSH keys using a config file.

Lets go through each step for setting up github and bitbucket account-

Step 1: ssh keys

Create any keypairs you’ll need. In this example I’ve named these key pairs as ‘id_rsa_github’ and ‘id_rsa_’bitbucket:

ssh-keygen -t rsa -C “"
ssh-keygen -t rsa -C “”

Step 2: ssh config

Set up multiple ssh profiles by creating/modifying ~/.ssh/config. Note the differing ‘Host’ values:

# For GitHub
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_github

# For BitBucket
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa_bitbucket

Step 3: ssh-add

You may or may not have to do this. To check, list identity fingerprints by running:

$ ssh-add -l

2048 1f:1a:b8:69:cd:e3:ee:68:e1:c4:da:d8:96:7c:d0:6f (RSA)
2048 6d:65:b9:3b:ff:9c:5a:54:1c:2f:6a:f7:44:03:84:3f (RSA)

If your entries aren’t there then run:

ssh-add ~/.ssh/id_rsa_github
ssh-add ~/.ssh/id_rsa_bitbucket

Step 4: test

To test you’ve done this all correctly, I suggest the following quick check:

$ ssh -T

Hi Saurabh! You’ve successfully authenticated, but GitHub does not provide shell access.

I hope this will save someone’s hair!!
