How Purple handles contractor and time-limited staff WiFi access
When a contractor walks onto your site on day one, they need network access. When their contract ends six weeks later, that access needs to go away. Simple in theory. In practice, most businesses handle this badly.
A shared password gets handed over on a sticky note. The contractor leaves. The password doesn't change. Six months later, someone wonders why an unknown device is still showing up on the network.
Purple's Staff WiFi solves this without extra admin work. Here's how.
The problem with temporary access today
Most Guest WiFi setups weren't designed for time-limited staff. You're choosing between two bad options:
1) Put them on the regular staff network, where you have to manually remove them when they leave. That depends on someone remembering to do it.
2) Put them on the Guest WiFi alongside actual visitors, where they share bandwidth, get no role-based access, and you lose any visibility into who's who.
Neither option works well for contractors, seasonal workers, or event crew who need more than guest-level access but shouldn't have permanent credentials.
How Purple handles it differently
Purple ties network access to identity, not passwords. When a contractor is added to your identity provider (Microsoft Entra ID, Google Workspace, or Okta), Purple picks that up through a SCIM integration and provisions them a certificate-based WiFi pass. They authenticate once through the Purple app and connect without typing a password.
That WiFi pass is personal and unshareable. It works on their device and only their device. It follows them across your entire site without re-authentication, which matters on large estates or multi-building campuses.
The automatic offboarding part
This is where it actually gets useful for contractors. When a contractor's end date arrives and they're disabled in your identity provider, the SCIM integration catches that change immediately.
Their access is revoked. No IT ticket required. No one has to remember.
Time-limited credentials without extra setup
Some contractors don't have a company device and won't be added to your identity provider at all. Purple handles this with Unique Identity Pre-Shared Keys (iPSK). These are individual credentials issued per device, not shared passwords.
The difference between an iPSK and a regular shared password: if one iPSK gets compromised, you revoke that one credential. The rest of the network is unaffected. With a shared password, everyone's affected the moment it leaks.
What you actually see on your end
Purple gives you dashboards that show who's on the network, when they connected, and from where. For IT teams managing contractors across a large site, that's the audit trail you need. You can see that a specific contractor connected on Tuesday at 9am and disconnected at 5pm, rather than just seeing an anonymous device.
That visibility also feeds into space utilisation. If you can see that a contractor team only uses two out of five rooms in a building, that's data you can act on.
Works with whatever hardware you already have
Purple doesn't require you to replace your existing network infrastructure. It uses RADIUS authentication, which is supported by Cisco, Aruba, Ruckus, Ubiquiti, and most enterprise-grade access points. You're not locked into a specific hardware vendor.
The short version
Contractor arrives, gets added to your identity provider, gets a personal WiFi pass through the Purple app. Contractor leaves, gets disabled in your identity provider, loses access automatically.
No manual steps. No tickets. No lingering credentials.
For businesses that rotate temporary staff regularly, that's a meaningful reduction in security risk and admin overhead.
