title: What are the consequences of changing the email linked to my ssh public key?
body: <p>I currently have one public/private pair of ssh keys that I mainly used for my college coursework. Since I linked my university email to the key upon creation, I would like to update it to my personal email for future projects.</p>
  
  <p>As <a href="https://stackoverflow.com/questions/24563677/best-practice-for-using-ssh-key-pair-with-different-groups">this similar post</a> notes, the email is simply a comment used to identify the key and does not affect commit attributions.</p>
  
  <p>If I modify my file directly in, ~/.ssh/id_rsa.pub, how will this affect its appearance on sites like GitHub and GitLab?
  For example, <a href="https://i.stack.imgur.com/J79uw.png" rel="nofollow noreferrer">here are my GitHub SSH settings with my old email</a>.</p>
  
  <p>Would I have to delete this key and reenter it in order for the email to update in the title? Or is the original email hardcoded into the key? Thanks.</p>
