Criterion sc2FA

Passkeys eliminate the need for two‑factor authentication, improving security and user experience

Team A
L: 5.000
Null: When considering authentication methods, passkeys have no effect on the necessity of two‑factor authentication
d: 0.00

No linked atoms.

When using passkeys, two‑factor authentication becomes unnecessary, thereby enhancing security and reducing user experience friction because it eliminates the need for a second factor
d: 5.00Σ +0.670
AtomWeight
Passkeys render two‑factor authentication unnecessary0.670

Criterion scEase

Passkeys provide a more familiar and transparent authentication experience compared to passwords

Team A
L: 5.000
Null: When considering user authentication, passkeys have no impact on the perceived ease of use compared to passwords
d: 0.00

No linked atoms.

When users authenticate, passkeys are perceived as easier and more familiar than passwords because they use biometric methods like face‑ID or fingerprint scanning that users recognize from phone unlocking and Apple Pay
d: 5.00Σ +0.450
AtomWeight
Passkeys can be cumbersome to use.-0.688
Passkeys use biometric authentication (face‑ID or fingerprint scanning) that users recognize from Apple Pay or unlocking their phone, making the authentication experience familiar0.450
FaceID or fingerprint biometrics can be used with passkeys to log in without remembering anything across all devices in the same ecosystem0.438
Chrome’s password manager and Apple’s ecosystem tightly integrate passkeys, enabling seamless use across a user’s devices0.250

Criterion scIntegration

Passkey integration into browser‑based applications and PWAs is challenging and device/browser dependent

Team A
L: 3.000
Null: When integrating passkeys into browser‑based or PWA environments, there is no impact on integration feasibility
d: 0.00

No linked atoms.

When deploying passkeys in browser‑based applications or PWAs, integration feasibility is reduced because it depends heavily on the device and the browser being used
d: 3.00Σ -0.050
AtomWeight
Chrome’s password manager and Apple’s ecosystem tightly integrate passkeys, enabling seamless use across a user’s devices-0.250
Passkey implementations vary between sites, making migration from an iPhone to an Android or between password managers clumsy or impossible.0.200

Criterion scPhishing

Passkeys provide phishing resistance by scoping credentials to a domain and using device‑provided security

Team A
L: 5.000
Null: When considering authentication methods, passkeys have no effect on phishing resistance
d: 0.00

No linked atoms.

When using passkeys, phishing attempts fail because credentials are scoped to a domain and device‑provided security prevents users from leaking passkey secrets even if they misunderstand how it works
d: 5.00Σ +1.475
AtomWeight
Device‑provided security prevents users from leaking passkey secrets, even if they misunderstand how it works0.750
Phishing resistance of passkeys is achieved by scoping credentials to a domain0.725

Criterion scSync

Passkeys enable seamless cross‑device login through ecosystem integration

Team A
L: 3.000
Null: When considering authentication methods, passkeys have no impact on cross‑device sync and ecosystem integration
d: 0.00

No linked atoms.

When using passkeys, users can log in across devices seamlessly because Chrome’s password manager and Apple’s ecosystem tightly integrate passkeys, enabling a single passkey across a user’s devices in many cases
d: 5.00Σ +1.925
AtomWeight
Chrome’s password manager and Apple’s ecosystem tightly integrate passkeys, enabling seamless use across a user’s devices0.625
FaceID or fingerprint biometrics can be used with passkeys to log in without remembering anything across all devices in the same ecosystem0.563
Users are already familiar with authenticator app approaches for two‑factor authentication that require them to keep devices synchronized with secrets0.313
Users often have passkey credentials spread across multiple systems that they are unaware of.0.225
Typical users use devices from multiple ecosystems, such as an Android phone, a Windows laptop, and a work Mac.0.200

Criterion scDeviceLoss

Decreasing device loss risk when passkeys are chosen strengthens Team B's case

Team B
L: 5.000
Null: When passkeys are used, device loss risk has no effect on B's case
d: 0.00

No linked atoms.

When passkeys are used, the risk of user lockout due to device loss or lack of backup is high, thereby weakening Team B's case
d: -5.00Σ +2.425
AtomWeight
A default login method must be able to function when a user's phone is dead or stolen; passkeys currently may not meet that requirement.0.887
Passkeys are tied to specific hardware or a vault that syncs across devices, so loss of that device can lock a user out.0.838
Most users do not have a second device, backup, or knowledge of services such as iCloud Keychain for passkey recovery.0.738
Passwords can be typed on any phone or laptop worldwide, even after the user's device is lost or stolen.-0.725
Typical users use devices from multiple ecosystems, such as an Android phone, a Windows laptop, and a work Mac.0.438
Passkey implementations vary between sites, making migration from an iPhone to an Android or between password managers clumsy or impossible.0.250
