How time-scoped access codes work

A permanent gate code has one fatal flaw: it never expires. Hand it to a guest, a cleaner, or a contractor and it keeps working long after the reason you shared it is gone. The usual fixes — changing the code, collecting keys, re-keying a lock — are exactly the chores smart access is supposed to remove.

Time-scoped access flips the model. Instead of a code that works forever, you create a code that works only during a window you choose.

A code with a start and an end

When you create a code in BuzzMeIn you attach it to a schedule: a one-off window for a weekend guest, a recurring weekday morning for a cleaning crew, or the exact span of a reservation pulled from your booking calendar. Outside that window the code simply does not open the door.

Because the window is part of the code, you never have to remember to turn it off. Check-out passes, the guest code stops working, and there is nothing to collect.

Checked over the call your box already makes

Your callbox already knows how to do one thing: place a phone call when someone presses your unit. BuzzMeIn answers that call. It plays a short greeting, listens for a keypad code or a spoken passphrase, checks it against the active schedule for that property, and — on a match — sends the same unlock tone your box expects.

No new panel. No wiring. No app for the person at the door to install. The whole exchange takes seconds, and every attempt is written to a timestamped entry log.

Why it is safer

• Nothing lingers. Access ends automatically, so an old code is a closed door.
• Everything is logged. You can see who came in and when, per property.
• Revocation is instant. Made a mistake? Deactivate the code and it stops on the next call.

Time-scoped codes are the difference between sharing a secret and granting an appointment. One you have to clean up after. The other cleans up after itself.
