I have multiple SSH keys on a single device.

// example
id_rsa_github_office.pub , id_rsa_github_personal.pub

How can I manage multiple SSH keys without conflict on a single device?

    Please be more specific about what you want. If you just want to "use both keys in one pc", why don't you just copy over the two `id_rsa*` files and store them under different names? The name is arbitrary. On the ssh command line you can specify an `-i identity_file` option to select between the two keys. Also in the `~/.ssh/config` you can configure to use one key for one ssh connection and the other for a second (or all other) ssh connection(s). If you search for these keywords, there's ample documentation on this on the net. – cfi Jan 06 '16 at 13:37

Create a SSH config file

When you have multiple identity files, create a SSH config file mechanisms to create aliases for your various identities.

You can construct a SSH config file using many parameters and different approaches.

The format for the alias entries use in this example is:

Host alias 
  HostName bitbucket.org 
  IdentityFile ~/.ssh/identity

To create a config file for two identities (workid and personalid), you would do the following:

Open a terminal window.
Edit the ~/.ssh/config file.

If you don't have a config file, create one.
Add an alias for each identity combination for example:

Host workid
HostName bitbucket.org
IdentityFile ~/.ssh/workid

Host personalid
HostName bitbucket.org
IdentityFile ~/.ssh/personalid

PS

Don't forget to load the keys to your github account.

Create config file inside the .ssh directory with name config.

Then inside the config file write down these configurations. Change the your-file-name to your SSH key file-name and change the your-host-name to your preferred host-name

Host <your-host-name>
 HostName github.com
 User git
 IdentityFile ~/.ssh/<your-file-name>

The config file should be looking something like this after the edit.

Then we will clone the same old way using a modified URL

$ git clone git@github-personal:GhostWolfRider/Angular-Admin-Dashboard.git
