The dangers of shared logins.
Shared accounts feel convenient. They destroy audit trails, leak with every turnover, and turn one small breach into a company-wide incident.
Shared logins feel practical — one account the whole team uses for social media, billing, or a shared inbox. In reality they're one of the worst habits a small business can have. They eliminate audit trails, they leak with every hire and every departure, and they turn a single phished account into a company-wide breach.
Why it's worse than it looks
When five people share a password, there's no way to know who did what. If someone deletes important files, posts something inappropriate, or wires money, you can't prove who. When the first of those five people quits, the password stays. Nobody rotates it until something breaks. By year three, ex-employees, contractors, and random freelancers still know the password to a live business account.
Real incidents we've unwound
“A small marketing agency shared a Meta Business Manager account for all four clients.”
Red flag: One employee's personal email was breached and the shared login was stored there. Attackers ran $18K in fake ads overnight before anyone noticed.
“A law firm had a shared admin@ inbox used by every partner and assistant.”
Red flag: Rather than investigating, the firm couldn't even tell which person had been phished. Forensics stalled for a week.
What to replace shared logins with
- Per-user licenses on every SaaS tool that supports them. Yes, it costs more. It's still cheaper than an incident.
- Single sign-on (SSO) for apps that support it, so access is tied to your identity provider.
- Shared mailboxes (not shared accounts) in Microsoft 365 or Google Workspace — everyone has their own login but can access the same mailbox.
- A password manager with shared vaults for the few things that can't be moved to per-user access.
Ready to clean it up?
We help businesses migrate from shared logins to per-user access all the time. Usually takes a week and removes a pile of risk.

Why admin rights matter.
Every employee running as a local admin is one bad click away from company-wide compromise. Least privilege is free and astonishingly effective.
