Passkeys: the end of passwords for your small business

Your employees juggle twenty passwords, reuse half of them, and end up writing one on a sticky note stuck to the monitor. That is exactly the weakness an attacker looks for. Passkeys change the equation: you sign in with your face, your fingerprint or your device PIN, and you never type a password.

Microsoft, Google and Apple have all been pushing this technology since 2024, and it is mature enough now to roll out in a small business. Here is what a passkey is, how it works in practice, and how to turn it on without wrecking your work habits, in Trois-Rivières and everywhere else in the Mauricie.

1. What is a passkey?

A passkey is a pair of digital keys generated by your device the moment you register it with a service. One part stays on the service’s server, the other never leaves your phone or computer. When you sign in, the device asks for your fingerprint, your face or the device PIN, then proves to the service that it is really you. No password to remember, no password to steal.

The big difference from a classic password: no shared secret travels anywhere. An attacker who intercepts the connection gets nothing usable, and a fake sign-in page is worthless, because the passkey is bound to the real site. That is what makes phishing essentially useless against it.

• You sign in with something you have (the device) and something you are (biometrics).
• The key only works on the legitimate site it was created for.
• Nothing to memorize, nothing to reuse from one service to another.

2. Why do passwords no longer hold up?

The password is sixty years old and it shows its age. The Canadian Centre for Cyber Security notes that password reuse remains one of the most frequent causes of account compromise in the country. One password stolen from a breached site, and the attacker tries it everywhere else. It is fast, it is automated, and it works more often than people think.

Phishing is the other big problem. An employee gets a fake Microsoft email, clicks, enters their credentials on a page that looks like the real one, and it is over. Even two-factor authentication by text message can be worked around by a patient attacker. A passkey cuts all of that short: there is simply no code and no password left to intercept.

• Weak or reused passwords remain the number one way in.
• Text message codes can be hijacked, unlike a passkey.
• Fewer password resets also means fewer calls to IT support.

3. How does it work, in plain terms?

Say an employee wants to turn on a passkey for her Microsoft 365 account. She goes into the security settings, chooses to add a passkey, and her phone asks her to confirm with a fingerprint. Done. The next time she signs in, the site offers the passkey, she approves with her finger or her face, and she is in.

The key can live in several places depending on your choice: in the phone, in the iCloud keychain, in the Google password manager, or on a physical FIDO2 security key. If it syncs through the cloud, it follows the employee across her devices. If you want something sturdier for administrator accounts, a physical key is still the strongest option.

What you need to get started

• Recent devices: Windows 11, macOS, iPhone or Android, kept up to date.
• A modern browser (Edge, Chrome, Safari) that supports the FIDO2 standard.
• Biometrics enabled on the device, or at minimum a device PIN.

4. Turning on passkeys in Microsoft 365 and Windows 11

For a small business, the logical starting point is Microsoft 365, because that is where the email and the files live. An administrator first enables the method in the Entra admin centre (the authentication policies), then each employee registers their passkey from the security page of their account. Microsoft documents the steps in detail, and the rollout can happen gradually, team by team.

One piece of field advice: do not remove passwords on day one. Let both methods coexist for a few weeks, long enough for everyone to register at least two keys (the phone and a backup physical key, for example). That way nobody gets locked out because they dropped their phone in the river.

• Enable the method in Entra, then test with a small pilot group.
• Ask each person to register two passkeys, never just one.
• Keep passwords active during the transition, then tighten afterward.

5. What does this change for a business in the Mauricie?

Beyond security, the most visible gain shows up in daily work. Your employees lose less time resetting forgotten passwords, and whoever handles IT gets fewer account lockout calls. For a Trois-Rivières company without a large IT team, that is time recovered every week.

The rollout is worth planning with someone who knows your equipment. A mix of old and new devices, employees working from home, shared accounts: each reality calls for an adjustment. Our managed IT services team assesses your environment, configures the authentication policies and supports your people, without interrupting work. If you want to talk it over, write to us through the contact page and we will look at it together.

• Fewer password resets, so fewer interruptions.
• Serious protection against phishing, the most common threat.
• A staged transition that respects your team’s pace.

Frequently asked questions

Are passkeys really safer than a password with MFA?

Yes, because there is no secret to steal and no code to intercept. The key is bound to the real site, so a fake sign-in page gives an attacker nothing. It is a step above a password paired with a text message code.

What happens if I lose my phone?

That is why you always register at least two passkeys, for example the phone plus a physical key or a second device. You sign in with the other one, then revoke the lost phone’s key from your account. Good planning prevents any lockout.

Does it work with Microsoft 365 and Google Workspace?

Yes. Microsoft 365, Google and Apple all support passkeys based on the FIDO2 standard. Most common online services accept them too, and the list grows every month.
