Do Guests Have To Register?
To place online bids, yes, guests are required to have a bidder record that contains an email address.
When a guest registers online, a bidder record is created in the system with their email and password.
Guests can be manually added on the dashboard and be sent a bidder invitation (to create a password) or an access token (no password is entered) to access the online website in either case an email address is required.
Only one bidder record should be created per email address - unless the bidders are linked (see Link vs Merge Bidders?). If two "unlinked" guests try to sign in using the same email address the software cannot identify which bidder is trying to sign in and will decline access.
