Article summary: Passwords and SMS codes are routinely captured by modern phishing kits, even when staff use multi-factor authentication. A passkey migration plan moves your business to cryptographic logins that attackers cannot replay, and the rollout can happen in phases without disrupting day-to-day work. The result is a quieter help desk and a meaningful drop in account takeover risk.
A staff member in your office gets a Microsoft 365 sign-in prompt. The page looks correct. The branding is correct. But the URL is one character off.
They enter their password and approve the MFA push. A minute later, an attacker is reading their email.
That scenario now has its own name: an adversary-in-the-middle attack.
For Canadian SMBs that have already invested in phishing-resistant cybersecurity controls, the next step is to remove the password from the equation entirely.
A passkey migration plan is how you do that without disrupting your team.
Why Passwords and Standard MFA Are No Longer Enough
Passwords get reused, written down, and phished. Standard MFA helps, but modern phishing kits intercept one-time codes in real time and replay them before they expire.
The Canadian Centre for Cyber Security has been tracking this shift directly.
Between 2023 and mid-2025, the Cyber Centre analyzed more than 100 adversary-in-the-middle phishing campaigns targeting Microsoft Entra ID accounts, finding widespread use of business email compromise techniques and trusted file-sharing services to evade detection.
The Cyber Centre’s ITSM.30.031 guidance identifies phishing-resistant MFA as one of the most effective controls against adversary-in-the-middle phishing attacks, because it prevents attackers from relaying or reusing authentication data captured through proxy-based phishing sites.
What Makes Passkeys “Phish-Proof”
Passkeys are cryptographic credentials stored on a device you control, such as a laptop, phone, or hardware key. Instead of sending a secret across the network, your device proves to the server that it holds a matching key. The key never leaves the device.
That single design choice removes an entire class of attacks.
A fake sign-in page can copy your logo and look identical to the real thing. It cannot copy a key it never sees. If the domain does not match, the authentication does not happen.
Three types of passkeys are common in business settings:
- Synced passkeys held in iCloud Keychain, Google Password Manager, or Microsoft Authenticator, which allow users to access credentials across their devices
- Device-bound passkeys, stored securely on a specific laptop or mobile device and not transferable
- Hardware security keys, such as YubiKey, often used for administrative access and high-value accounts
The FIDO Alliance’s 2025 Passkey Index found that passkey sign-ins average 8.5 seconds, compared with 31.2 seconds for traditional authentication methods. The bigger advantage is not speed, but architecture: there is no shared secret for an attacker to steal.
A Practical Passkey Migration Plan
You don’t need to migrate everyone at once. A staged rollout is more manageable and easier to support.
Inventory your accounts and apps
List the systems your team signs into every day: Microsoft 365, Google Workspace, accounting software, your CRM, line-of-business tools, and admin portals. Note which already support passkeys. Most major platforms now do.
Pick a starting group
Begin with the accounts that carry the most risk, then expand. The HID and FIDO Alliance 2025 State of Authentication survey found that 87% of organisations are actively deploying, piloting, or rolling out passkeys, with early deployments often focused on privileged users and people with access to sensitive data.
Administrators, finance staff, and anyone with broad access to email or files are good first candidates.
Enroll step by step
Set aside fifteen minutes with each team member. Guide them through registering a passkey on their phone or laptop, then add a second on a backup device. Most operating systems walk users through the process.
Once a passkey is in place, set their account to allow passkey sign-in by default. Leave the password option available during the transition, then remove it after a defined period.
Plan for recovery
Every passwordless system needs a plan for what happens when a device is lost.
For most teams, that means registering at least two passkeys per person, on separate devices. For administrators, Microsoft’s guidance recommends two break-glass accounts secured with hardware keys and stored offline. Document the recovery process so a missing phone never becomes a help desk emergency.
Where Canadian Compliance Fits
Canadian privacy law does not name passkeys directly, but it does set expectations that apply.
PIPEDA (the Personal Information Protection and Electronic Documents Act, Canada’s federal private-sector privacy law) requires organisations to protect personal information with safeguards appropriate to its sensitivity.
For regulated sectors such as healthcare in Ontario, PHIPA imposes more stringent safeguard requirements.
Cyber insurance is moving the same way.
Cyber insurance underwriters are increasingly asking about phishing-resistant authentication at renewal, and some Canadian carriers offer more favourable terms to organisations that deploy it. IBM’s 2025 Cost of a Data Breach Report consistently finds that stolen credentials are one of the most common initial access vectors, and that the cost of a breach in Canada runs into the millions of dollars.
If you have already worked through related controls such as a security audit for your office smart devices or a cleanup of unsanctioned browser extensions, a passkey migration plan fits the same pattern. Visibility, then control, then a routine that keeps both in place.
Ready to Plan Your Move?
A passkey migration plan does not need to be disruptive. It takes a clear inventory, a staged rollout, and a recovery process your team can rely on. Most Canadian small businesses can finish the first phase in a few weeks.
Data First Solutions works with businesses to plan and run passkey rollouts inside Microsoft 365 and Google Workspace, including pilot scoping, user enrolment, and the policies that make the change stick.

Article FAQs
What is a passkey in plain language?
A passkey is a digital credential held on a device you control, such as your phone or laptop. It replaces the password and one-time code at sign-in by using cryptography to prove your identity, without sending anything an attacker can intercept.
Will my team need new hardware to use passkeys?
For most accounts, no. Phones and laptops made in the last few years already support passkeys natively, and Microsoft 365 and Google Workspace support them out of the box. Hardware security keys are useful for administrators and high-risk accounts.
How long does a passkey migration plan typically take?
For a Toronto SMB with under 50 staff, a structured rollout usually takes four to eight weeks, depending on how many applications are in scope and how many users need backup devices.
Does passwordless authentication meet Canadian privacy requirements?
PIPEDA requires safeguards appropriate to the sensitivity of the data. Passkeys meet a higher bar than passwords or SMS codes because they cannot be phished, which matters for organisations handling client, patient, or financial data.
