One Door. One Credential.

Preventing Tailgating & Piggybacking
It happens quickly. An employee badges into a secure area and, trying to be courteous, holds the door open for the person walking behind them. Someone carrying boxes asks for help getting through a locked entrance. A familiar-looking contractor follows a staff member through an access-controlled door.
 
Most of the time, there's an innocent explanation—but one moment of courtesy can unintentionally bypass an important layer of security. 
 
Tailgating and piggybacking occur when someone enters a controlled area by following an authorized person rather than using their own approved access credential. In museums, libraries, archives, historic sites, universities, and other cultural institutions, this can potentially provide unauthorized access to collections, offices, storage areas, mechanical spaces, or other sensitive locations. ️ ️
 
 What should staff watch for?

•  One person, one credential. Each individual entering a controlled area should use their own authorized access method whenever institutional policy requires it.
•  Don't let packages become a pass. Someone carrying boxes, equipment, or supplies may genuinely need assistance—but their identity and access authorization should still be verified.
•  Don't rely on a badge alone. A visible ID badge does not necessarily mean someone is authorized to enter every area of the facility.
•  Be aware of who follows you through a secured door. Before allowing someone to enter behind you, make sure they are authorized to be there.
•  Be polite but verify. Security doesn't require confrontation. A simple “Hi, can I help you get checked in?” or “You'll need to badge in here as well” can reinforce security while maintaining excellent visitor and customer service.
•  Report concerns. If someone attempts to bypass access controls or repeatedly tries to enter restricted areas, follow your institution's established reporting procedures.

 Remember:

Access control technology only works when we support it with good security habits.
Holding a door may feel courteous, but when it comes to a restricted area, the safest courtesy is helping someone follow the proper access procedure.
