Small businesses have spent years hearing the same advice: use strong passwords and turn on multi-factor authentication. That advice is still important, but the latest warning from the FBI shows why it may no longer be enough by itself.
On May 21, 2026, the FBI issued a public warning about Kali365, a phishing service designed to target Microsoft 365 accounts. What makes this threat especially concerning is that it can help attackers gain access without simply “stealing the password” in the old-fashioned way. Instead, it abuses legitimate Microsoft sign-in flows and captures access in a way that can get around weaker authentication habits.
For a small business owner, that matters because Microsoft 365 is often more than email. It can hold your calendars, files, Teams chats, invoices, customer information, and internal approvals. If one employee account is taken over, the business impact can spread quickly.
This is not just another fake-email problem.
Microsoft’s own 2026 threat reporting shows that phishing is still evolving fast. Attackers are using cleaner design, smarter timing, QR codes, CAPTCHA pages, and sign-in flows that look legitimate enough to lower people’s guard. Microsoft also documented recent device-code phishing campaigns that used real Microsoft sign-in pages as part of the trick.
That is exactly why small businesses should stop thinking about account protection as just a password issue. The real issue is whether your staff can be tricked into approving the wrong sign-in session.
A passkey is a more secure way to sign in that uses your device, plus something like your fingerprint, face, or PIN, instead of relying on a reusable password.
The reason security professionals are pushing passkeys so hard is simple: they are designed to be phishing-resistant. In other words, they are much harder to use on a fake lookalike website or malicious approval flow.
Microsoft said this month that passkey adoption is accelerating, with the FIDO Alliance estimating 5 billion passkeys already in use worldwide. Microsoft is also expanding passkey support across its ecosystem, including broader Microsoft Entra capabilities in late May 2026.
That does not mean every small business has to flip a switch overnight. It does mean the conversation has changed. Passkeys are no longer an “enterprise someday” project. They are becoming a practical security upgrade for businesses that rely on Microsoft 365 every day.
If your company uses Microsoft 365, now is a good time to review a few basics:
There is also a practical business benefit here. Better sign-in protection can reduce account lockouts, password reset headaches, and the stress of constant sign-in prompts. For many small teams, a simpler and safer sign-in experience is easier to maintain than a patchwork of passwords, codes, and exceptions.
The goal is not perfection. The goal is to make your business much harder to impersonate, trick, or quietly access.
