How guests log in: PIN, not a one-time code
The Guest Portal uses a 4-digit PIN sent with the link, not the email one-time-code login used by the Renter Portal.
Why a PIN instead of a code by email
A short stay is a single, low-friction interaction — the owner already vouches for who received the link, so there's no separate "prove you own this email" step like the Renter Portal's one-time code. The PIN is baked directly into the send-link email, so the guest opens the link and types the 4 digits already in front of them. No second email, no waiting.
Changing and regenerating the PIN
Once inside, the guest can change their PIN to something they'll remember — useful if they want to share access with a co-traveler by voice rather than forwarding the email. As the owner, you can also regenerate the PIN yourself at any time from the booking's Guest Portal panel; this immediately invalidates the old one, so use it if you suspect it leaked. Regenerating is separate from reopening a closed portal, which deliberately keeps the existing PIN unchanged.
If the guest forgets their PIN
The login screen has a "Forgot your PIN?" link that resends the current PIN to the email already on file for that booking — never to an address typed in on the spot. If no email is on file for any renter on the booking, nothing is sent and the guest is told to contact you directly.
