====== Using Multiple Githup Accounts on One Computer ======

I am writing for the Windows operating system, but the logic should work for other operating systems as well. With 5 simple steps we will be able to switch between accounts whenever we want.

  - Generate SSH keys for all accounts
  - Adding SSH keys to SSH Agent
  - Adding SSH public keys to Githup
  - Creating setting file and preparing Host inputs
  - Using different accounts when copying Githup repos

===== Generating SSH Keys for all accounts =====

For Windows, you need to be in the user folder. But we don't need to worry about that since we will use the Git Bash command line. We can get things done using Unix code.

<code>
C:\Users\__SENIN_KULLANICI_ADIN__\
</code>

  - Open Git Bash and type the following codes in order.


<code bash>
cd ~
mkdir .ssh
# If the folder already exists, the above will give an error. If it already exists, we will use that folder.
cd .ssh
eval `ssh-agent -s`
</code>

  - Create ssh keys for each account in the relevant folder using the following code.

<code bash>
ssh-keygen -t rsa -C "__MAIL_ADDRESS__" -f "__GITHUP_USER_NAME__"
</code>

<WRAP round info>
The ''%%-C%%'' key here is for comments to help with identification. ''%%-f%%'' is the name of the file where the key will be saved.
</WRAP>

<WRAP round important>
The mail address you write here should be the non-emailable mail address that githup defines for us. It is not mandatory, but it is better not to use our main mail address in any git process to avoid confusion.
</WRAP>

<WRAP center round info 60%>
After adding the keys, there should be a private and a public file for each account in the **.ssh** folder.

The public key will have the extension ''%%.pub%%'' and the private key will not have an extension. Both will have the same name as the one after ''%%-f%%''.

Once you have created a key for each of your accounts, you can continue.

</WRAP>

===== Adding SSH Keys to SSH Agent =====

While still in .ssh on the command line, you can add the switches to the agent with the following command.

<code bash>
ssh-add __GITHUP_USER_NAME__
ssh-add __GITHUP_USER_NAME__
</code>

===== Adding SSH Public Key to Githup =====

Open the resulting ''.pub'' files with any text editor and copy the contents.

[[https://github.com/settings/keys|https://github.com/settings/keys]] by going to Add from **New SSH key**. You can write whatever you want in //Title//.

===== Creating and preparing a Config File =====

  - Go to Bash and enter the command ''touch config''.
  - The above code will create a file named **config** in that folder without extension. Open that file with any text editor and paste the following into it.

<code bash>
	#__GITHUP_USER_NAME__ account
	Host github.com-__GITHUP_USER_NAME__
		HostName github.com
		User git
		IdentityFile ~/.ssh/__GITHUP_USER_NAME__
		
	#__GITHUP_USER_NAME2__ account
	Host github.com-__GITHUP_USER_NAME2__
		HostName github.com
		User git
		IdentityFile ~/.ssh/__GITHUP_USER_NAME2__
</code>

Edit the username parts to suit you. You can increase the number as much as you want.

===== Cloning Githup Repos Using Different Accounts =====

You can clone with the command below or you can clone directly over HTTPS.

<code bash>
git clone git@github.com-{__GITHUP_USER_NAME__}:{__REPO_OWNER_USER_NAME__}/{__REPO_NAME__}.git
</code>

You need to set user settings for each repo separately to determine which account will be used for commits. Global settings can only be used for a single account. Always do the following for all your existing repos and any repos you clone in the future.

<code bash>
     git config user.email "__GITHUP_MAIL_ADRESI__"
     git config user.name "__GITHUP_USER_NAME__"
     
     git config user.email "__GITHUP_MAIL_ADRESI_2__"
     git config user.name "__GITHUP_USER_NAME2__"
</code>

Of course you can increase the number.

Finally, we need to add remote origin to be able to use **pull** and **push**. Run the following command for each repon.

<code bash>
git remote add origin git@github.com-__GITHUP_USER_NAME__:__GITHUP_USER_NAME__
     
git remote add origin git@github.com-__GITHUP_USER_NAME2__:__GITHUP_USER_NAME2__
</code>
