iAnnotate features in-app integration with remote accounts hosted by Dropbox or WebDAV. While setting up an account, iAnnotate’s popup box will prompt you for the account’s name, associated email address, and password.

If you leave the password field blank, then iAnnotate prompts you for a password each successive time that you attempt to access that account (rather than automatically logging into it).

To change this behavior to an automatic login, tap and hold the account in the Connectivity tab, tap Edit, and then enter the correct password in the field.
