-If you have no SSH keys registered, there should be a notification asking you to provide your SSH public key. In the Workbench top navigation menu, look for a dropdown menu with your email address in upper right corner. It will have an icon such as <span class="badge badge-alert">1</span> (the number indicates there are new notifications). Click on this icon and a dropdown menu should appear with a message asking you to add your public key. Paste your public key into the text area provided and click on the check button to submit the key. You are now ready to "log into an Arvados VM":#login.
