Spreadsheets vs. Password Managers

Comparing spreadsheets and the browser's saved passwords against a real business password manager — what breaks, what it costs, and which to choose.

The short version

Three ways to store passwords, in a nutshell

Spreadsheet

Easy to start, hard to control

Quick to set up and familiar — but once the file is shared, copies spread and there's no clean way to revoke access or see who has what.

Browser passwords

Convenient for individuals

Great for one person's own logins. Limited central business control — no company vault, and credentials often walk out with the personal account.

Password manager

Built for a business

Individual access with centralized management: per-item sharing, auditing, and one-click offboarding when someone leaves.

From file to breach

Copied & sharedEmail, drive, USBuncontrolled
→
Leak or leaveNo revocation pathevery login exposed

A password manager breaks this chain at step one: per-item access + instant revocation instead of one shared file.

One spreadsheet leaked

A single file can expose every system it holds a login for
  • Email
  • Banking
  • Microsoft 365
  • QuickBooks
  • Vendor portals
  • Firewall
  • Servers

One employee compromised

With a managed password manager, exposure is contained
Only the credentials that person was actually permitted to use — depending on how access is configured — not the whole company's logins.
Problem 1

The "protected" Excel sheet

Why it feels safe but isn't: Modern Excel can encrypt a workbook with a password, and that encryption is real. But encryption alone doesn't make a spreadsheet a safe way to manage business credentials — everyone who knows the file password can see the entire list, copies spread outside your control, and there's no per-credential access, auditing, or simple offboarding.

IssueDetail
"Protect Sheet" ≠ encryptionExcel's Protect Sheet / Protect Workbook options only discourage editing — they don't encrypt anything and are trivially removed. Only Encrypt with Password actually protects the file.
One password for everythingEven with real encryption, anyone who has the file password can open every credential in it at once — and if it leaks, the whole list is exposed.
No audit trailNo way to see who opened the file, when, or which passwords they copied.
Version chaosCopies spread via email, OneDrive, desktops, USB drives — uncontrolled once shared.
No revocationSomeone leaving means rotating every password in the file, not just removing access.
No sharing granularityEveryone with the file password sees everything — no per-account limits.
Problem 2

The "protected" Google Sheet

Google Sheets has no native password-to-open feature at all — unlike Excel, there's no file-level encryption option to turn on in the first place.

IssueDetail
No real protection existsSheets has no "enter a password to open" mechanism.
"Protect ranges" only blocks editingAnyone with access can still view every password in the sheet.
Security = sharing settingsAn accidental "anyone with the link" share exposes everything.
Copy / print / export still workProtection doesn't actually contain the data.
Same all-or-nothing accessNo way to share just one login with one person.
Bottom line: both spreadsheet tools rely on trust and manual discipline, not real access control.
Problem 3

What about Chrome's saved passwords?

Google Password Manager feels like an upgrade — autofill, sync, free. For a person, it works well. But it wasn't designed to give a business centralized control of its credentials — and unless every account is company-managed, your logins can end up somewhere you can't see, audit, or revoke.

IssueDetail
Tied to the individual's accountCompany credentials get saved to an employee's Google account. If that account isn't company-managed, the business loses control the day they leave.
Not built for business sharingGoogle supports limited password sharing, but there's no company vault with team permissions and central ownership — so logins still get texted, emailed, or pasted into a sheet.
Limited business controlsIt lacks the centralized vault permissions, access management, auditing and offboarding controls that a dedicated business password manager provides.
One account protects many credentialsA compromised Google account or an unlocked, signed-in device puts everything stored behind it at risk — MFA and device security become the whole ballgame.
One-click export to plain textChrome's "Export passwords" dumps every saved login into an unencrypted CSV file in seconds — no approval needed, and nothing tells the business it happened.
Websites & apps onlyIt handles website and app passwords well — but Wi-Fi credentials, recovery codes, license keys, server logins and secure notes still need a home, and they land back in the spreadsheet.
No audit trail for the businessNobody can answer "who accessed the bank login, and when?"
Bottom line: the browser's password manager protects a person. It was never designed to protect a company.

Pros & cons

Spreadsheets vs. password managers

Excel / Google Sheets

Pros

  • ✓ Free — already in Microsoft 365 / Workspace
  • ✓ Familiar interface, nothing new to learn
  • ✓ Quick to build for a small list

Cons

  • – No real encryption (Excel) or none at all (Sheets)
  • – All-or-nothing access, no per-login limits
  • – No revocation without rotating every password
  • – No audit trail; copies spread uncontrolled
Business password manager

Pros

  • ✓ Strong vault encryption
  • ✓ Per-item sharing, not whole-vault
  • ✓ Instant revocation on offboarding
  • ✓ Full audit logs, built-in 2FA storage

Cons

  • – Small recurring per-user cost
  • – Requires initial setup and employee onboarding
  • – Users need to adopt a new workflow
The middle ground

The browser password manager, honestly

Google / browser saved passwords

Pros

  • ✓ Free and already built in
  • ✓ Convenient autofill on that person's devices
  • ✓ Far better than reusing one password everywhere

Cons

  • – Company logins often end up in individuals' accounts, outside the business's control
  • – Sharing is limited — no company vault with team permissions
  • – Lacks the admin controls, auditing and offboarding a business needs
  • – One compromised account or unlocked device exposes everything saved
  • – Anyone at the keyboard can export it all to a plain-text file in one click
  • – Websites & apps only — Wi-Fi, servers and license keys end up in a spreadsheet anyway
Bottom line: keep it for personal browsing. For company logins, a business password manager gives you what neither spreadsheets nor the browser can: per-person access, an audit trail, and an off-switch for the whole company's credentials.
Pricing

What it actually costs

Business password managers typically run a few dollars per user per month — and typically offer shared vaults, secure credential sharing, admin controls, and centralized offboarding.

OptionSticker priceThe real cost
Spreadsheet"Free" — bundled with Microsoft 365 / WorkspaceIT hours on resets, offboarding rotations, and breach cleanup
Browser saved passwordsFreeCompany logins scattered across personal accounts you can't see or revoke
Business password managerA few $/user/moPredictable — and offboarding takes one click instead of an afternoon
For a small team, the entire tool usually costs less per month than one hour of emergency IT cleanup. We'll recommend the right one for your setup — we're not tied to any single vendor.

"A locked filing cabinet with one key that everyone shares."

That's a protected Excel file — and it can't be re-keyed. A password manager is a smart lock: different access per person, every entry logged, and revoked instantly when needed. We'll set it up and migrate your logins, usually in week one.
