The Password is Dying: How Passkeys Reached 5 Billion Users by 2026

For decades, the cybersecurity industry has chased a singular, elusive goal: killing the password. In 2026, the data suggests they have finally succeeded.[7]

The FIDO Alliance estimates that 5 billion passkeys are now in active use worldwide, marking a permanent shift in how humans authenticate their digital lives.[1]

According to the State of Passkeys 2026 report, 90% of consumers are now aware of the technology, and 75% have enabled a passkey on at least one account.[1]

Passkeys replace traditional passwords with a cryptographic mechanism known as FIDO2 or WebAuthn. Instead of typing a memorized string of characters, users simply unlock their device using a biometric scan—like a fingerprint or facial recognition—or a local PIN.[5]

The underlying security relies on public-key cryptography. When a user creates a passkey for a website, their device generates a unique cryptographic key pair.[4]

The public key is sent to the website's server, while the private key remains locked inside the device's secure hardware enclave. Because the private key never leaves the device, there is no "shared secret" stored on a corporate server.[5]

This architectural shift effectively neutralizes phishing and credential stuffing. Even if hackers breach a company's database, they only steal useless public keys, and fake login pages cannot trick a passkey into handing over credentials.[4]

The consumer tipping point arrived when major platform providers integrated passkeys directly into their operating systems. Google accelerated this transition in late 2023 by making passkeys the default sign-in option for personal accounts.[3]

By embedding passkeys into the native "sync fabrics" of iOS, Android, and Windows, tech giants solved the technology's biggest historical hurdle: device loss. If a user drops their smartphone in a lake, their passkeys are safely restored on a new device via their cloud keychain.[3][7]

Following the consumer rollout, the enterprise and government sectors received a crucial green light in July 2025. The U.S. National Institute of Standards and Technology (NIST) released Revision 4 of its SP 800-63 Digital Identity Guidelines.[2]

The updated NIST guidelines officially recognized "syncable passkeys" as meeting Authenticator Assurance Level 2 (AAL2). This regulatory blessing allowed heavily regulated industries, such as finance and healthcare, to deploy passkeys for their workforces without violating strict compliance frameworks.[2]

For businesses, the return on investment has been immediate. Organizations deploying passkeys report a 45% reduction in employee login times and a 35% drop in helpdesk tickets related to password resets.[1][6]

However, security researchers caution that passkeys are not entirely invulnerable. Academic studies analyzing FIDO2 deployments have found that when users are required to set a fallback PIN for hardware security keys, up to 40% choose simple, easily guessable numbers.[4]

Furthermore, the reliance on synced passkeys introduces a new centralized point of failure. Because passkeys are backed up to Apple, Google, or Microsoft cloud accounts, the security of a user's entire digital life is now inextricably linked to the security of that primary ecosystem account.[4][7]

Cross-ecosystem friction also remains a challenge. While transferring a passkey from an old iPhone to a new iPhone is seamless, moving credentials between competing ecosystems—such as from Apple to Android—still relies on clunky QR code scans or third-party password managers.[6][7]

Despite these growing pains, the trajectory of authentication is set. The password is no longer the default front door to the internet; it is rapidly becoming a legacy fallback, reserved only for old systems and rare account recovery scenarios.[7]
