Once you have your license, you can log in to Cornell's E-signature service. 

1. Go to the Adobe Sign Sign In page.
2. In the Sign In window, enter your netid@cornell.edu email address, then click Continue. Do not use the Apple/Google/Facebook options. You MUST use your netid@cornell.edu email address to sign in, even if you normally use an email alias such as john.doe@cornell.edu.
   
3. You may see a Select an Account window. If you do, chose Company or School Account
   
4. You will see a standard Cornell University CUWebLogin window. Enter your Cornell NetID and password, then click Login.
5. You will see the standard Cornell University Two-Step Login window. Verify your account with your two-step authentication method of choice.

If you follow any links from other Adobe products about sending a document for signature, you will end up at Adobe's public login page. As soon as you enter an email address ending in @cornell.edu, a button will appear that says Sign in with your Cornell NetID and password. Click Sign In to be taken to the CUWebLogin page.
