On October 14, 2025, the Access Profile sign-on experience on McGraw Hill’s Access Medicine (hosting platform of Harrison’s Principles of Internal Medicine Online) will be changing for improved security.
Please note: institutional authentication methods are not changing. This change only applies to users who have created personal Access Profiles on the platform to bookmark content and access other functionality.
From October 14th, you will need to sign in with your email address, as usernames will no longer work.
You can still create a new account after October 14th but you won’t be able to access an existing account (including bookmarks and other saved content) unless your account has a valid email address listed.
What You Need to Do Now:
Check your Access profile and make sure you have a valid email address listed — ideally your institutional email address.
To log in, click MY PROFILE in the top right corner and sign in.

Select “My profile” on the dashboard and you will be taken to a form where you can check that you have a valid email address listed.

Add or update your email address before October 14 to ensure you can sign in after the transition.
Please email the ebooks@cambridge team if you have any questions.
