Within Teamwork Projects, you can use your API Key to log in as an alternative to your username and password.
To locate your API key, click your profile icon in the top right corner of your site, and select Edit My Details from the dropdown menu.
In the edit details modal, go to the API & Mobile tab, and click the Show your Token button to the left.
When you select Show your Token, you can then copy your API key.
