What Is Passkey Migration and How Can It Help Your Team Eliminate Passwords?

Your team relies on passwords that get forgotten, reused, and reset constantly. Every month, IT fields password reset requests. Every year, breach reports list stolen credentials as the leading cause. There is now a more effective path — and it does not require users to memorize anything. Passkey migration is the process of moving from traditional passwords to passkeys: phishing-resistant authentication that uses your device's built-in security instead of a shared secret. Small businesses in McAllen and across the RGV can start this migration today without any new hardware.

Why Passwords Are Still the Biggest Risk

More than 80% of data breaches involve compromised credentials, according to the Verizon Data Breach Investigations Report — a figure consistent year after year. Passwords are shared secrets that must be stored somewhere, and secrets that get stored eventually get stolen. Even SMS-based MFA codes have a known weakness: modern phishing kits can intercept a one-time code in real time. Passkeys close that gap by design.

What a Passkey Actually Is

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. When you log in, your device uses biometrics (Face ID, fingerprint, or Windows Hello) to sign a challenge from the server. A passkey cannot be phished, cannot be reused, and cannot be exposed in a server-side breach. The FIDO Alliance reports that more than 15 billion online accounts now support passkey sign-in.

What Passkey Migration Actually Means

Passkey migration is not a single cutover — it is a gradual transition running passwords and passkeys in parallel until passkeys are established across the platforms that matter. For most teams running Microsoft 365 or Google Workspace, the infrastructure is already in place. Microsoft enabled passkeys through Entra ID and made them the default sign-in for new accounts in May 2025. Google has supported passkeys for Workspace accounts since 2023.

How to Approach Migration Without Disrupting Your Team

Start where support already exists

Begin with administrators and power users — they reset passwords most often, have the highest-risk access, and will give honest feedback on friction before rollout reaches the wider team. Map your current tools against passkey support before communicating any change.

Run passwords and passkeys in parallel

Users authenticate with passkeys on enrolled devices and fall back to passwords on any device not yet enrolled. Running both methods simultaneously gives time for adoption without locking anyone out mid-project.

Plan for platforms that are not ready yet

Not every tool supports passkeys today. For those, a password manager generating unique credentials is the right bridge. IT Umbrella Group helps McAllen-area clients manage this transition phase as part of our Microsoft 365 support service.

The Business Case Beyond Security

Google reports that passkey sign-ins are four times more successful than password-based logins, with sign-in speeds approximately 20% faster. Fewer failed logins means fewer helpdesk calls and fewer interruptions. NIST's 2025 update to SP 800-63-4 now requires phishing-resistant authentication as a mandatory option for high-assurance access — making passkey migration a compliance step as well as a security improvement.

Frequently Asked Questions

Do passkeys work across all devices and platforms?

Most modern devices support passkeys natively — iPhone, Android, Windows, and Mac all include built-in support. Chrome, Safari, and Edge support passkey sign-in. Microsoft 365, Google Workspace, GitHub, and Apple ID are fully ready.

What happens if a user loses the device their passkey is stored on?

Passkeys sync across enrolled devices through cloud keychains. If a device is lost, the passkey is recoverable on any other device signed into the same account ecosystem.
