Visiting app.dimensions.ai and selecting Login in the top right corner will now lead you to the new and simplified login page where you can enter your email address (see below). When you select Next we automatically check what kind of account you have and forward you to the correct page - whether that is simply entering your password, or being forwarded to your organizational single sign-on (SSO) page.

If you previously used a ReadCube Papers account to log in to Dimensions, you can still log in with your password, but the Dimensions and ReadCube Papers accounts will no longer be directly linked. You can change your password on your account details page.
