An October industry report points to wider use of passkeys. The practical question is how to use them while keeping a reliable way back into your accounts.
A sign-in method is only useful if people actually use it. In an October 15 update, the FIDO Alliance estimated that 7 billion passkeys were in use worldwide and described a shift from simply making passkeys available toward using them routinely.
The 2026 Passkey Index announcement draws on 15 participating consumer services. FIDO says more than a third of successful sign-ins in that data now use a passkey. That is evidence from the participating services, not a claim that one third of every login on the internet uses the technology. The 7 billion estimate counts passkeys, not individual people.
Why the change matters for phishing
Passkeys use cryptographic authentication instead of asking a person to type a reusable password into a website. The Cybersecurity and Infrastructure Security Agency's guidance identifies FIDO/WebAuthn as a phishing-resistant approach, supported through authenticators built into devices or separate security keys.
That addresses a weakness in familiar sign-in routines: a convincing imitation page can ask for a password or a one-time code. A passkey is tied to the legitimate service in a different way. It is an improvement to the authentication process, not a guarantee that every device, account-recovery process or online transaction is safe.
For U.S. shoppers approaching the holiday season, that distinction matters. Stronger sign-in protection does not establish that a store is genuine, an offer is honest or a payment request is appropriate. Account security and judgment about a transaction remain separate tasks.
Know where your passkey lives
Microsoft's passkey FAQ explains the role of device-based authentication and how a passkey differs from a password. The precise setup varies by service, operating system and credential manager. Some credentials can sync through a provider; others remain tied to a particular device or security key.
Before changing a critical account, identify which option the service is offering and how you would regain access if a device were lost. Read the provider's recovery instructions while you can still sign in normally. Check that your recovery information is current, and protect recovery codes or backup keys according to the service's guidance.
A useful first test is an account whose settings you understand and can revisit. Create the credential through the service's own security settings, confirm that it works and note which device or manager holds it. Avoid making several unfamiliar changes at once and then discovering that you cannot tell which step caused a problem.
Convenience needs a clear recovery plan
FIDO's report suggests that the design of the sign-in screen also affects adoption: users are less likely to use a passkey when a password or code is offered first. For businesses, that makes rollout partly a design and support problem, not just a technical switch.
For individuals, the goal is simpler: a sign-in routine that is harder to phish and easier to manage. Keep software updated, use official account settings and understand the backup path before relying on a single device. The most reassuring security improvement is one you can explain to yourself without guessing what happens if your phone disappears.
