Why credentials need managing
Every key, card, fob and alarm code is a small piece of trust. In a business with a handful of staff it is easy to let these accumulate informally: a spare key given to a part-timer, a code passed along by word of mouth, a card never returned. Over time nobody can say with confidence who can get in. That uncertainty is the real risk, because it makes it hard to notice a problem or to respond when something goes missing.
Managing credentials does not need special software. It needs a clear list, a few rules and the habit of following them. The goal is that access always matches the current staff and what each person actually needs.
Decide what each person needs
Start from the principle of giving people the access their job requires and no more. A cashier may need the front door and the register area. A stock clerk may need the stockroom. A manager may need everything, including the ability to arm and disarm the alarm. Few staff need access to the safe, the server cabinet or the records room.
Where your system supports it, set up levels or schedules. Many access control options let you limit a card to certain doors or hours, so a weekend worker cannot enter on weekdays, for example. Even where equipment is basic, you can follow the same idea with different keys for different rooms, which is where key control becomes useful.
Issuing credentials
When someone joins:
- Record their name, the type of credential issued, its serial or ID number and the date.
- Issue a personal credential, not a shared one. Unique alarm codes and cards let you see who did what and let you cancel one person’s access without disturbing everyone else.
- Explain the rules: do not lend, copy or photograph credentials, and report loss immediately.
- Have the person sign for physical items such as keys, cards and fobs.
- Help them choose a code that is not obvious. Birthdays, repeated digits and simple sequences are poor choices, and codes should not be written down where others can see.
Keep this record somewhere secure with limited access. It includes sensitive information, and where personal data is involved, rules differ by place, so check what applies to you.
For keypads, the guidance on keypad entry and code management covers how codes are set and changed in more detail. For smart locks, temporary codes and logs can make issuing and removing access easier, though they bring their own trade-offs.
Reviewing access regularly
Set a review schedule, such as every quarter, and tie it to the broader routines in your daily security practices. At each review:
- Compare the list of credentials against the current staff list and remove anyone who has left.
- Check that each person still needs the access they have, especially after changes of role.
- Look for credentials that have not been used in a long time, if your system keeps logs. Unused access is a candidate for removal.
- Confirm that physical items can be accounted for, and follow up on anything missing.
- Review who holds administrator rights over the alarm or access system, and keep that group small.
Seasonal and temporary staff, contractors and cleaners deserve special attention. Their credentials are often issued quickly and then forgotten. Give them an end date when you issue the credential, and note it on your calendar.
Revoking access promptly
The most important moment is departure. Whether someone leaves on good terms or not, act on the day they finish, or earlier if circumstances call for it.
- Collect keys, cards, fobs and any other items, and record their return.
- Cancel the person’s alarm code and disable their card or app access.
- Check whether they knew shared codes, such as a safe combination or a gate code, and change those if so.
- Consider changing or rekeying a lock if a key was not returned or cannot be accounted for.
- Remove their access to any cloud accounts or remote access tools connected to cameras and alarms, since these are credentials too.
When an employee is dismissed in difficult circumstances, it is usual to remove access before or at the time they are informed. Handle the personal side with care and consider speaking to an employment adviser, since rules differ by location.
Lost and stolen credentials
Tell staff that reporting a loss quickly is always welcome and never punished harshly. A hidden loss is far worse than a reported one. When a credential goes missing, disable it at once, record the incident and decide whether locks need changing. A lost card can usually be canceled instantly. A lost key to a lock that is not part of a restricted system may mean rekeying.
Digital credentials count too
Passwords for camera recorders, alarm apps and management software are access credentials as well. Use strong, unique passwords, turn on two-factor authentication where it is offered, and give each person their own login if the system allows. Shared logins make it impossible to tell who did what, and they are hard to revoke. Basic cybersecurity habits matter here, and the same offboarding steps apply to digital accounts as to physical ones.
Where biometrics or identity verification are used, extra care is needed because a fingerprint cannot be changed as a password can. Think through storage, consent and legal requirements before using them, and ask a professional if unsure.
Keep it light enough to maintain
A short spreadsheet or paper register, a quarterly review and a firm departure checklist are enough for most small businesses. Complex systems that nobody updates are worse than simple ones that are maintained. No arrangement can guarantee that credentials will never be misused, but accurate records and quick removal of access reduce the chances and make any problem easier to investigate.
