People, Logins & Permissions

The one-login shortcut, and what it really costs

Plenty of offices share one login — “the password is on the sticky note, everybody uses the same one.” It feels like saving trouble. It actually spends it, in three currencies:

• Detective work. Sooner or later a number is wrong and somebody asks, “How did this get entered?” Rental Books keeps a history of changes. If everyone signs in as “Office,” the history says Office did everything — which means nobody did, and there’s nobody to ask. With separate logins, the history names a person, and nine times out of ten the answer is a quick “oh, that was the Johnson payment, I put it on the wrong unit” and it’s fixed in a minute.
• The right keys for the right people. The part-time helper who enters rent payments doesn’t need the ability to delete accounts, change past months, or see everything the owner sees. Permissions are how you hand someone exactly the keys their job needs — not the whole ring, just in case.
• People leave. When an employee goes, a shared password forces an ugly choice: change it and re-teach everybody, or don’t and leave a working key with someone who no longer works there. With separate logins, the admin turns off one login. Done. Everyone else’s day doesn’t change.

How it works in Rental Books

Each set of books keeps its own list of people. The office admin — usually the person at the computer that holds the books — manages it from the Users screen:

• Add a person with their name and what they’re allowed to do, and send their invitation (the sharing guide, Part 2). Each person picks their own password; the admin never knows it and never needs to.
• Change permissions any time — someone’s job grows, their access grows with it.
• Reset a forgotten password — the person picks a new one at their next sign-in. No master key, no sticky note.
• Turn a login off when someone leaves. Instant, and it touches nobody else.

Keep the number of full-power admin logins small — one or two people who genuinely run the office. And one old-fashioned tip that still works: write the admin password on paper, seal it in an envelope, and keep the envelope somewhere locked. Computers fail at the worst moments; paper in a safe is a fine backup plan.

The Tuesday helper, as a story

Say you hire help who comes in Tuesdays to enter payments and file. She gets her own login, with permission to do payments and tenants — not payroll-type changes, not deleting history, not the owner reports. She signs in as herself at the shared front-desk computer (and doesn’t tick “keep me signed in,” because that desk is shared — see the sharing guide, Part 3). If a payment lands on the wrong tenant in March, the history shows her login and the date; you ask, she remembers, it’s fixed. When the arrangement ends in June, one click turns her login off. No passwords changed for the whole office, no wondering what’s still out there. That’s the entire system, working the way it’s supposed to.
