4x Faster Logins, Zero Passwords: A Practical Guide to Passkey Migration

Your team runs on passwords. Some are strong, some aren’t, and most have been reused somewhere over the years. Every month your IT support fields reset requests. Every year, the same breach reports name stolen credentials as the leading cause. Passwords have had sixty years to prove themselves, and the verdict is in.

There’s now a better path, and it doesn’t ask anyone to memorise a thing. Passkey migration is the move from traditional passwords to passkeys: a phishing-resistant sign-in that uses your device’s built-in security instead of a shared secret. It’s practical, it’s already supported by the platforms you use, and the business case is hard to argue with.

Why passwords are still the biggest risk

More than 80% of data breaches involve compromised credentials, a figure that barely moves year to year, according to the Verizon Data Breach Investigations Report. The reason hasn’t changed: a password is a shared secret that has to be stored somewhere, and secrets that get stored eventually get stolen.

Multi-factor authentication (MFA, the second check after your password) cut that risk a lot and remains an important baseline. But SMS codes, still the most common form of MFA, have a known weakness. Modern phishing kits can grab a one-time code in real time: a convincing fake login page captures both the password and the code, then uses them on the real site before the session expires. Passkeys close that gap by design. A fraudulent page simply can’t trigger a login on your real device, because the credential is mathematically tied to the genuine web address.

What a passkey really is

A passkey is a cryptographic credential. Instead of a shared password sitting 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 your face, fingerprint, or a PIN (Face ID, Windows Hello, and the like) to sign a challenge from the server, and the server checks it against the public key. No password is ever sent anywhere. That means a passkey can’t be phished, because a fake page can’t trigger your real device. It can’t be reused, because it’s bound to one web address. And it can’t leak in a server breach, because the private half never exists outside your device.

Passkeys run on open standards backed jointly by Apple, Google, and Microsoft, and the FIDO Alliance reports that more than 15 billion online accounts now support passkey sign-in, double the year before. This isn’t a fringe technology. It’s where the major platforms have already gone.

What migration really means

Passkey migration isn’t a single switch you flip. It’s a gradual transition that runs passwords and passkeys side by side until passkeys are established across the accounts that matter. A sensible plan covers three things: which platforms already support passkeys, which users to start with, and what the fallback is for tools that aren’t ready yet.

For most teams on Microsoft 365 or Google Workspace, the groundwork is already laid. Microsoft enabled passkeys through Entra ID and made them the default sign-in for new accounts in May 2025. Google has supported them for Workspace since 2023. If you’re in either camp, you can begin without buying any new infrastructure.

How to roll it out without disrupting your team

Start where support already exists. Begin with administrators and power users. They reset passwords most often, hold the highest-risk access, and will give you honest feedback on any friction before it reaches the wider team. Map your current tools against passkey support first. Microsoft 365, Google Workspace, and most major identity providers are fully ready. Start there and leave the laggards for a later phase.

Run both methods in parallel. The most common mistake is treating this as a hard cutover. Let people sign in with a passkey on enrolled devices and fall back to a password on anything not yet enrolled. Running both at once gives adoption time to happen without locking anyone out mid-project.

Plan for the tools that aren’t ready. Not every app supports passkeys today. For those, a password manager generating unique credentials is the right bridge. It removes the password-reuse risk now, and when those tools add passkey support later, migration becomes a single enrolment step rather than a change in habit.

The business case beyond security

Security is the main driver, but the day-to-day benefits are real and measurable. Google reports that passkey sign-ins are four times more successful than password logins and around 20% faster. The gain 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 a small team that can’t afford them.

There’s a compliance angle too. The updated US NIST guidance now requires phishing-resistant sign-in as a mandatory option for high-assurance access, so for businesses working toward those standards, passkey migration is also a tick in that box. It’s the same direction we covered in passkeys: the future of secure sign-ins on Windows 11, now a practical project rather than a future idea.

From password-dependent to passwordless

You don’t need to rip out everything overnight. Most businesses across the Northern Beaches already have the core pieces in Microsoft 365, which means the first move is simply mapping what supports passkeys today and starting with a small group.

At Vaelis IT we help small businesses across the Northern Beaches and North Shore plan and run exactly this kind of migration, alongside the broader cybersecurity and Microsoft 365 work that keeps a team secure without enterprise overhead. We’ll build a passkey plan that fits how your business actually runs, not a templated rollout pushed onto everyone.
