Managing SSH keys can become cumbersome as soon as you need to use a second key. On top of that, you might be using a different key pair for accessing your own private server.
For example, you might be using one SSH key pair for working on your company's internal projects, but you might be using a different key for accessing a client's servers. Though it's considered good practice to have only one public-private key pair per device, sometimes you need to use multiple keys or you have unorthodox key names. You now have a public and private SSH key pair you can use to access remote servers and to handle authentication for command line programs like Git.
