Is it safe to share access codes through AI messaging?

Yes, when done correctly. Modern AI messaging platforms use a multi-layer security approach:

How secure access code sharing typically works:

1. Reservation-window gating — access codes are only shared within the booking window (between check-in and check-out)
2. Channel-bound conversation — the messaging channel ID (phone / Telegram chat ID) identifies the guest's conversation
3. Encryption — messages are encrypted in transit (TLS) and at rest
4. Restricted topics — host-configured topics can require host approval before any code is shared

Important honest note: chat-based identity verification is limited. If your access code is static (the same code for every guest), anyone who has previously stayed knows it. The most reliable mitigation is a smart lock that issues a fresh, time-bound PIN per reservation.

What's safer than the alternatives:

• Leaving a lockbox code in a public Airbnb message (visible to Airbnb support staff)
• Texting codes via SMS (can be intercepted, no verification)
• Putting codes in a publicly accessible listing description
• Taping codes to the property door

Best practices:

• Use dynamic codes that change with each guest (smart locks with temporary codes)
• Set codes to expire after checkout
• Never share codes with unverified contacts
• Have a backup access method (hidden key in secure location)
• Review who accessed codes in your messaging dashboard
