Within Teamwork Projects, contacts are used to store details for reference and cannot log in to your site to interact with projects.

You can upgrade an existing contact to a standard user, so they can log in and be assigned tasks.

Go to the People tab at the top of your site.

From the list of people on your site, select the contact you want to upgrade, to view their profile page.

In the top right corner of their profile, click the options (three dots) button, and select Upgrade to User Account from the dropdown menu.

You will be asked to confirm if you want to upgrade the contact to allow them to log in.

Once you have confirmed, you will be prompted to send an invite email to the new user. You can do this later if you wish by clicking No, Thanks.

Whether you choose to send an email or not, on the next page you will see that they have now been upgraded to a user.
