Multiple bitbucket accounts

This blog post describes a straightforward way to add multiple ssh keys to a single computer and use one ssh key per a bitbucket account. It is much clearer than the official bitbucket documentation. To summarize:

First, make sure you have a default account setup through a tutorial like this one on Github.

For the second account:

1. Create a new ssh key:

   ssh-keygen -f ~/.ssh/<your second account name> -C "<you email>"
   

2. Add the ssh key:

   ssh-add ~/.ssh/<key file name> 
   

3. Use pbcopy < ~/.ssh/<your second account name>.pub to copy the public key and add this key to your bitbucket account (in the settings area)

(On Windows you can copy the ssh key using ssh-keygen -f ~/.ssh/<your account name> -c "<your email>" | clip or on Linux you can follow these instructions.)

4. Add the following to your ~/.ssh/config file. The first sets the default key for bitbucket.org. The second sets your second key to an alias bitbucket-account2 for bitbucket.org:

   Host bitbucket.org
     Hostname bitbucket.org
     IdentityFile ~/.ssh/id_rsa
   
   Host bitbucket-account2
     Hostname bitbucket.org
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/<your second account name>
   

5. You can now clone projects with your default account the same way as before:

   git clone [email protected]:username/project.git
   

6. To clone a project with the second identity, replace bitbucket.org with the Host that you specified in the ~/.ssh/config file (i.e. bitbucket-account2 above):

   git clone git@bitbucket-account2:username/project.git
   

That's it!

You may get this error if you haven't added the key to the key manager (ssh-agent). To do this:

ssh-add ~/.ssh/tech

By the way, if you have multiple Bitbucket accounts, you'll need a unique key for each account. You can't reuse keys.
