Should I use my personal email in my ssh public keys?
<p>Reading Github's <a href="https://help.github.com/articles/generating-ssh-keys/" rel="noreferrer">Generating SSH keys</a> tutorial, I saw this on the <a href="https://help.github.com/articles/generating-ssh-keys/#step-2-generate-a-new-ssh-key" rel="noreferrer">Step 2: Generate a new SSH key</a>:</p>

<pre><code>ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
</code></pre>

<p>What bothers me is the <code>"your_email@example.com"</code>. I know that is just a comment and it is even optional. But I was wondering, is it safe to put your email address there? Because I think it is recommended to put your machine, not your email, something like <code>"my-machine@home"</code>.</p>

<p>I already used public keys following that tutorial, so my email address is in some of my public keys. Should I fix it? Or it is not a problem?</p>
