The Center for Open Science (COS) and Tufts University have become partners to offer an Open Science Framework (OSF) Institutions site for the Tufts community.
If you DO NOT already have an OSF account, you can log in to OSF using your Tufts credentials.
If you already have an account, you can add your Tufts information to that account so that you can Sign In with your Tufts credentials and affiliate your existing projects with Tufts.
Go into your Profile page (which you can get to by clicking on your name and choosing My Profile) and click on the link in the top right of the page that says Edit your profile.
Choose Account Settings from the menu on the left and find the text entry box that allows you to enter a new email address. In that box, enter [Tufts username]@tufts.edu (for example, klee56@tufts.edu). You will be sent a confirmation email to your Tufts email account.
Follow the instructions in the email, and click the link to merge your accounts. You will then be able to Sign In through Tufts and to affiliate projects with Tufts.
