One code for everyone seems convenient until a cleaner stops visiting or a family member shares it with someone else. Changing that code affects every authorized person. Individual codes, when the lock or alarm supports them, let the owner make a narrower change and keep the rest of the household's routine intact.

Assign each credential to a named person and a clear purpose. Use the device's supported user-management tools rather than inventing a numbering system in an unsecured document. The user list can record who has access without storing the secret code itself.

Choose credentials that meet the product's requirements and are not obvious personal information. Do not reuse a banking PIN or an account recovery code. Sharing an owner login is also unnecessary merely because someone needs to open a door. Administrative privileges and ordinary entry should be considered separately.

The log may become easier to interpret, but keep its limits in mind. A record associated with a person's code shows that the credential was used. It does not prove who physically entered, whether someone followed them or whether the code had been shared. Avoid turning an access history into an assumption about a person's movements.

Review permissions when routines change. A regular visitor may need access only on certain days, while a resident needs a different schedule. Check what the exact product supports and whether changes have reached the lock. An edit saved in an app is not always evidence that an offline device has received it.

Explain the arrangement to users. They should know not to pass their code around and whom to contact if it may have been exposed. They also need the normal locking procedure and any separate alarm instructions. A technically valid code is only one part of a usable arrival.

When a person no longer needs access, remove their credential and verify the result through the supported process. Check related doors and systems too. Keeping this small list current is easier than maintaining one shared secret whose audience becomes less certain every year.
