How to Safely Share Rental Property Access Codes with Guests

You just got a new Airbnb booking. Now comes the part every host dreads — sending your door code, Wi-Fi password, and a wall of check-in instructions through a messaging app. You copy-paste the same info for the hundredth time, hit send on iMessage, and hope for the best. But that door code now lives permanently in someone else's phone.

There has to be a better way.

What Guests Actually Need

Every check-in package typically includes the same set of sensitive details:

• Door or keypad code — the single most critical piece of info
• Wi-Fi network name and password
• Parking instructions — spot number, permit details, or street parking tips
• Building access code — for apartments, condos, or gated communities
• Check-in and check-out times
• Emergency contact info
• House rules — quiet hours, trash, pets, smoking policy

That is a lot of sensitive information to just drop into a text message.

The Problem with Current Methods

Most hosts default to the easiest option. But easy does not mean safe.

The biggest risk? Using the same door code for months. Every past guest, their friends, and anyone who saw a forwarded screenshot still has access to your property.

A Better Approach: Expiring Secret Memos

The most practical solution is to put all your check-in information into a password-protected memo that automatically expires on checkout day.

Here is how it works with LOCK.PUB:

1. Create a secret memo — include your door code, Wi-Fi password, parking info, house rules, and anything else the guest needs
2. Set an expiration date — match it to the checkout date so the link dies automatically
3. Send the link — share it through Airbnb messaging or email
4. Send the password separately — text it via iMessage or Messenger

This way, each guest gets a unique link. After checkout, the information is no longer accessible — even if they bookmarked it.

Best Practices for Rental Hosts

Beyond how you share information, here are habits that protect your property long-term:

• Rotate door codes between guests — yes, it is extra work, but it eliminates the biggest vulnerability
• Use smart locks with temporary codes — many models let you generate time-limited PINs that expire automatically
• Set up a guest Wi-Fi network — keep your personal devices on a separate network
• Include emergency numbers in the memo — your number, a local contact, and relevant emergency services
• Test the link yourself — open it on your phone before sending to make sure everything reads clearly

With LOCK.PUB, you can build a check-in template and recreate it for each booking in under a minute. The memo holds all the details, and the expiration ensures nothing lingers after the stay.

Wrapping Up

Hosting is a hospitality business, but it is also a security responsibility. The information you share with guests — door codes, building access, alarm codes — deserves more protection than a plain text message.

Start your next guest check-in at LOCK.PUB. Create a password-protected memo, set it to expire on checkout day, and give your guests exactly what they need — nothing more, nothing longer than necessary.
