If you sign a document using the digital signatures feature or the digital signature tool, you will be prompted to log in to your profile (if you have not already done so) before you can sign the document. To log in to a profile: 1 Choose Tools > Self-Sign Security > Log In. (If you are already logged in to a profile, this command changes to Log In As Different User. If you have multiple profiles, use this command to log in to one of your other profiles.) 2 Choose a profile.The pop-up menu lists the most recently opened or created profiles. Or click Find Your Profile File, and browse to find a profile. 3 Enter your password, and click Log In. 4 If an alert appears confirming that you are logged in, click OK.Your Acrobat Self-Sign Security preference settings determine whether this alert appears. To log out of a profile: Choose Tools > Self-Sign Security > Log Out . About signature fields When you sign a document, your signature and the related information are stored in a signature field embedded on the page. A signature field is an Acrobat form field. You can add a signature field to a page as you sign, or you can use the form tool to create an empty signature field that can be signed later. When you create a signature field with the form tool, you can have Acrobat execute a script or lock all fields in the document when it is signed.You can also customize the field in several other ways. For information on creating empty signature fields with the form tool, see "Creating signature fields" on page 150. Note: If you're signing an existing field, be aware that the document author may have put duplicates of the field on other document pages. For example, sometimes a field is copied to the same place on every page. You need to sign the field only once, and your signature will appear in all occurrences of the field. This is sometimes done to allow quick initialing of every page in a document. Adding signatures to a document You can sign a document in several ways, both visibly and invisibly. Invisible signatures do not appear in the document, but they are visible in the Signatures palette. (In Acrobat 5.0, invisible signatures are added to the page of the document currently being viewed when the signature is added; in Acrobat 4.0, invisible signatures were added only to the first page of a document.) Note: If you delete a page that carries a signature, visible or invisible, the signature is deleted also. When you add a signature with Acrobat Self-Sign Security as your signature handler, your signature is verified automatically. Adding a signature does not affect the verification status of existing signatures in the document. For more information on the appearance or status of digital signatures in Acrobat Self-Sign Security, see "Verifying signatures" on page 203. Using Help | Contents | Index Back 201
