Account Tab

The Account Tab is where you manage settings, subscriptions, and resources across your projects. There are 5 tabs under under Account Tab.



Account settings


Most of the entries under Account settings are self-explanatory. Here are a few additional notes.

  • Your password is needed to change your email address.
  • Your password is needed to create or change the API key for your account. See CoCalc API documentation to learn about the API.
  • The Newsletter checkbox doesn’t do anything yet. We don’t send out a newsletter.
  • Sign Out of CoCalc using one of the orange “Sign Out” buttons. You will be asked to confirm your selection.
  • Choosing the red Delete Account... button will cause a warning window to pop up. Confirmation is required before proceeding.

  • Use one or more of the options under Linked accounts if you want to sign in with Facebook, GitHub, Google, or Twitter. You can also unlink online accounts from CoCalc in this section. To sign in with a linked account, choose the icon for Facebook, GitHub, Google, or Twitter under the blanks for Email address & Password at upper right in the sign-in screen.

Other settings

CoCalc allows you to specify dark mode for all windows in “Other settings”. See the News update on dark mode for more information.

Editor settings

Most options under “Editor settings” are self-explanatory. Here are additional details.

SSH keys

This section assumes you have created an SSH key pair as described in SSH Keys.

Click the gear icon next to your name at upper right to open Account Settings. Choose the tab “SSH Keys” and note the form for adding a key at right. Enter a title for the key in the Title field. Specify a title that is meaningful to you for the key pair you are using, for example John’s CoCalc Key. Copy the public key into the Key field. To do this, open the file for your public key on your local computer. For example, if you are using macOS or Ubuntu, you could open a terminal and type something like the following, depending on the name of your public key file. cat ~/.ssh/ Use your mouse to highlight the contents of the key file, then copy and paste it into the Key area. saving the entry.

Click Add SSH Key. Your key is now saved for that account and will work for all projects for which that account has owner or collaborator status. As with the previous section, the user@hostname string needed for the ssh command consists of the project id with hyphens removed for the user, and ‘’ for the hostname, and can be found just below the caption Use the following username@host: in the ‘SSH Keys’ section of project status tab.
