Voter Accounts are unique to one (1) voter. Each Voter Account is identified by its unique email address.
If you go into your Voter Account and change the content, it will not revert back to what you originally had, nor will it keep mulitiple sets of data distinct from each other. For example, if you create your Voter Account, and then login and change all the data to reprint a form for your partner or spouse, you have effectively changed all the content of the account to be that of another voter.
Please do not share your Voter Account. Each voter should start from the beginning of the registration process and create their own Voter Account. It is an optional feature of the system.
Summary: One voter per email address for each Voter Account.
