Contractors, agency workers, cleaning crews, and maintenance vendors keep most buildings running, yet they are usually the least carefully managed people on the access list. Temporary staff often get a spare card from a drawer or a shared door code. That is where the security gaps start.

Why temporary access is harder than employee access

An employee has one start date, one role, and usually one manager. Temporary access is messier. A cleaning crew rotates workers without notice. An agency sends a different person when the regular one is ill. A maintenance vendor needs the plant room on Tuesday mornings only. A contractor's project ends two weeks early, and nobody tells facilities.

Each situation invites the same shortcuts: shared credentials, open-ended access, and cards that never come back. The result is an access log that shows "Contractor Badge 4" instead of a real name.

The building blocks of safe temporary access

Every credential has an end date

The most effective control is the simplest: no temporary credential without an expiry. When the end date is set at the moment of provisioning, access switches off automatically when the contract ends, whether or not anyone remembers. Extending a contract becomes a deliberate decision, not a default.

Scope access by door and by hour

A cleaner working evenings does not need the server room at 10 a.m. A lift engineer does not need the finance floor. Temporary credentials should be scoped to the specific doors, areas, and time windows the job requires. With cloud access control, those schedules are set once and enforced at every reader, so a credential simply does not open doors outside its approved scope.

One named sponsor for every contractor

Every temporary worker should have an internal sponsor: the manager who requested the access and is accountable for it. The sponsor approves the scope and confirms extensions. Without one, contractor access tends to belong to nobody.

One person, one credential

Shared codes and pooled badges make every entry anonymous. Each agency worker or technician should get an individual credential, even for a single week.

Replace plastic cards with mobile credentials

Physical cards are a weak fit for temporary staff. They get lost, handed to a colleague, or simply never returned. A digital credential in Apple Wallet or Google Wallet solves most of that: it is issued remotely before the first shift, tied to one person's phone, and revoked from the dashboard without anything to collect. See our guides to wallet-based access and cards versus wallet credentials, or the wallet pass page.

Turn door entries into verified contractor hours

Here is the part many companies miss: when access control and attendance live in the same system, a contractor's door tap is both an access event and an hours record. That makes it straightforward to check a vendor's monthly invoice against actual arrival and departure times, per person and per site, rather than trusting a timesheet filled in after the fact. It is the principle behind using door access as a time clock, applied to people off your payroll. It also discourages the contractor equivalent of buddy punching, where one worker's badge covers for another.

Offboard the moment the contract ends

Contractor offboarding often has no checklist at all. With expiry dates set up front, most engagements close themselves. For early terminations, the sponsor or an admin revokes access from the cloud dashboard, and the change applies to every door at every site straight away. The discipline in our employee offboarding guide applies here too.

Keep an audit trail you can actually use

When a security review or client asks who had access to a site last quarter, the answer should include contractors by name, their sponsor, their permissions, and their actual entries. Door logs and compliance reports and live entry monitoring give that view in one place. One-off guests fit visitor management better; recurring contractors need proper profiles. Add a review of active temporary credentials to every attendance audit.

A simple checklist for temporary access

  • Individual credentials only. No shared codes or pooled badges.
  • An end date on every credential. Extensions approved by the sponsor.
  • Door and hour scopes. Only what the job requires.
  • Mobile credentials where possible. Nothing physical to lose.
  • Hours from the door. Check invoices against entry and exit records.

Frequently Asked Questions

How should temporary access for contractors and agency staff be set up?

TimeClock 365 lets an admin create a contractor or agency worker profile with a start date, an end date, a named internal sponsor, and a defined set of doors and hours. The credential only works inside that scope and stops working automatically when the end date passes, so nobody has to remember to switch it off. Every entry is logged against the individual person rather than a shared or generic contractor badge.

Why use mobile or wallet credentials instead of plastic cards for contractors?

TimeClock 365 can issue contractors a digital credential in Apple Wallet or Google Wallet instead of a plastic card. Temporary cards are the ones most likely to go missing, get passed between workers, or never come back at the end of a job. A wallet credential is tied to one person's phone, can be issued remotely before the first shift, and is revoked from the dashboard in seconds, with nothing to collect.

Can door access records be used to verify contractor invoices?

TimeClock 365 is the only platform that combines attendance management and door access control in a single cloud system, so the badge-in at the door is also the contractor's hours record. When a cleaning company or maintenance vendor invoices for a month of work, a manager can compare the billed hours against actual on-site arrival and departure times per person and per site, instead of relying on the vendor's own timesheets.

What happens when a contractor's engagement ends early?

TimeClock 365 lets an admin or the sponsoring manager change the contractor's end date or revoke the credential immediately from the cloud dashboard, and the change applies to every connected door at every site. There is no card to chase and no local reader to update. The profile, its access history, and its attendance records remain available for audits and invoice checks after access is closed.

Is TimeClock 365 secure enough to manage third-party access?

TimeClock 365 is certified to ISO/IEC 27001:2022 and keeps a complete audit trail of who approved each contractor, which doors and hours were granted, and every entry event recorded. The platform runs in 12 languages across 20+ countries and is used by 3,000+ companies, and teams can test contractor workflows with a 14-day free trial before rolling them out.
