Generate an API Key
Edited
You can generate an API Key at any time by clicking the gear icon and selecting 'API Access.'
Scroll down to Personal Access Tokens, and click the + icon to generate a new key.
You will be prompted to give your token a name, and then you will be shown the token.
The token is only shown ONCE. If you close the modal you will need to generate a new key if you mis-copied the original.
