Quicken ID, data file, and Mobile and Web Sync
These are the important points to note about your Quicken ID, data file, and Mobile and Web Sync:
Every data file is associated with a Quicken ID.
Multiple data files can be associated with a single Quicken ID.
If multiple data files are synced to mobile, you can select the file you wish to use when you sign in to Quicken Mobile or Web.
