TL;DR: Passkey migration is the gradual move from passwords to passkeys, a phishing-resistant login that uses your device’s built-in security instead of a shared secret. Passkeys can’t be phished, reused, or stolen in a server breach. For teams on Microsoft 365 or Google Workspace, the infrastructure is already in place. Run passwords and passkeys side by side, start with high-risk users, and bridge unsupported apps with a password manager.
Your team locks everything down with passwords. Some are strong, some are weak, and most have been reused somewhere over the years. Every month, IT fields reset requests. Every year, the same breach reports name stolen credentials as a leading cause. There’s now a better path, and passkey migration is how you get there without asking anyone to memorize a thing.
Passkey migration is the process of moving from traditional passwords to passkeys, a form of phishing-resistant authentication that uses your device’s own security instead of a shared secret. It’s practical, it’s already supported by most major platforms, and the business case is hard to argue with.
This isn’t a far-off idea. The pieces are already in your environment, and a planned rollout fits neatly into proactive managed IT services.
Why Are Passwords Still the Biggest Risk?
Passwords are still the biggest risk because they’re a shared secret that has to be stored somewhere, and stored secrets eventually get stolen. Sixty years in, the pattern hasn’t changed. Stolen credentials remain one of the most common ways attackers get in, a point the Verizon Data Breach Investigations Report makes year after year.
Multi-factor authentication helped, and it’s still an important baseline. But SMS codes, the most common form of MFA, have a known weakness. A modern phishing kit can intercept a one-time code in real time. A fake login page captures your password and the code, then uses both on the real site before the session expires. That gap is the same one adversary-in-the-middle attacks exploit.
Phishing-resistant authentication closes that gap by design. A passkey makes it technically impossible for a fake page to trigger login on your real device, because the credential is tied to the legitimate website address. Pairing that with ongoing security awareness training gives your team both a technical and a human defense.
What Is a Passkey?
A passkey is a cryptographic credential. Instead of a shared password stored on a server, your device creates a matched pair of digital keys when you register with a service. The private key stays on your device and never leaves it. The public key goes to the service.
When you log in, your device uses a fingerprint, Face ID, Windows Hello, or a PIN to sign a challenge from the server. The server checks the signature against the public key. No password is ever sent.
That design removes three classic failure points at once. A passkey can’t be phished, because a fake page can’t trigger authentication on your real device. It can’t be reused, because it’s bound to one website. And it can’t be exposed in a server breach, because the private key never exists outside your device. Passkeys are built on the open FIDO2 and WebAuthn standards, backed jointly by Apple, Google, and Microsoft. The FIDO Alliance reported that more than 15 billion online accounts now support passkey sign-in, double the year before.
What Does Passkey Migration Actually Mean?
Passkey migration isn’t a single cutover. It’s a gradual move that runs passwords and passkeys side by side until passkeys are established across the accounts and platforms that matter most. The goal is steady progress, not a risky overnight switch.
A migration plan usually covers three things: which platforms already support passkeys, which users to start with, and what fallback exists for tools that aren’t ready yet.
For most teams on Microsoft 365 or Google Workspace, the foundation is already there. Microsoft made passkeys the default sign-in for new Entra ID accounts in May 2025, and Google has supported passkeys for Workspace since 2023. If you’re in either ecosystem, you can start without buying new infrastructure.
How Do You Migrate Without Disrupting Your Team?
You migrate without disruption by starting small, running both login methods at once, and bridging the gaps. Treat it as a phased rollout, not a flip of a switch.
Start where support already exists. Begin with administrators and power users. They reset passwords most often, carry the highest-risk access, and will give you honest feedback on friction before the wider team is involved. Map your tools against passkey support first. Platforms like Microsoft 365, Google Workspace, GitHub, and most major identity providers already support passkeys fully, so start there and leave the rest for later.
Run passwords and passkeys in parallel. The most common mistake is treating migration as a full cutover. Instead, let people use passkeys on enrolled devices and fall back to a password on any device that isn’t enrolled yet. Running both at once gives adoption time to happen without locking anyone out mid-project.
Plan for tools that aren’t ready. Not every app supports passkeys today. For those, a password manager that generates unique credentials is the right bridge. It removes the password-reuse risk now, and when those apps add passkey support later, migration becomes a single enrollment step. Teams with internal IT can lean on co-managed IT support to keep the phases on track.
The Business Case Beyond Security
Security is the main reason to move, but the operational wins are real and measurable. Google’s own data shows passkey sign-ins are about twice as fast and four times more successful than passwords. The improvement comes from removing friction: no mistyped passwords, no waiting on SMS codes, no lockouts from an outdated credential.
Fewer failed logins means fewer helpdesk calls and fewer interruptions for everyone. That’s a direct saving on IT time and a real boost to productivity.
There’s also a compliance angle. The 2025 update to the NIST SP 800-63-4 digital identity guidelines now requires phishing-resistant authentication as a mandatory option for high-assurance access. For teams working toward those standards, passkey migration isn’t only a security upgrade, it’s a step toward compliance. Building it into a clear security strategy makes both benefits easier to capture.
From Password-Dependent to Passwordless
Three things are worth remembering. Passwords remain the most common way attackers get in, and no amount of complexity rules fixes that. Passkeys close the phishing gap by design, not by adding another step. And migration is a gradual, low-risk process that most businesses can start today with tools they already own.

Frequently Asked Questions
What is passkey migration?
Passkey migration is the gradual process of moving your team from passwords to passkeys, a phishing-resistant login method. Rather than a single cutover, it runs passwords and passkeys side by side until passkeys are established on the platforms that matter most. The goal is to reduce password risk without locking anyone out during the change.
Are passkeys really more secure than passwords?
Yes. A passkey can’t be phished, because it only works on the real website it was created for. It can’t be reused across sites, and it can’t be stolen in a server breach, because the private key never leaves your device. That removes the three ways passwords most often get compromised.
Do passkeys work with Microsoft 365 and Google Workspace?
Yes. Microsoft made passkeys the default sign-in for new Entra ID accounts in May 2025, and Google has supported passkeys for Workspace since 2023. If your team uses either platform, you can begin migration without buying new infrastructure. Our cybersecurity essentials guide covers how this fits a broader identity strategy.
What happens to apps that don’t support passkeys yet?
For tools without passkey support, a password manager that creates unique credentials is the right bridge. It removes the password-reuse risk now, and when those apps add passkey support, switching becomes a simple enrollment step rather than a behavior change.
How long does passkey migration take?
It varies by team size and how many apps you use, but because it runs in parallel with passwords, there’s no hard deadline or risky cutover. Many teams start with admins and power users, then expand over weeks or months. The phased approach is what keeps it low-risk and low-disruption.
