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 +0.920
AtomWeight
Passkeys render two‑factor authentication unnecessary0.670
Passwords without a second factor pose an unacceptable security risk, a risk also reflected in European regulation on banking logins0.250

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 +1.163
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
When a passkey is lost or a user needs to recover an account, most websites still provide a password or SMS code as a fallback, so the presence of these weak fallback mechanisms undermines the phishing‑resistance that passkeys claim to offer and means users maintain both strong and weak authentication methods simultaneously, adding complexity without eliminating the weak link.-0.313
When a fallback password or SMS code is available, the phishing resistance offered by passkeys is nullified, which strengthens Team B's case
d: -5.00

No linked atoms.

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 sc2FA_B

Passkeys replace 2‑factor authentication, improving security and user experience

Team B
L: 5.000
Null: When considering authentication methods, passkeys replacing 2‑factor authentication has no effect on the overall security and user experience
d: 0.00

No linked atoms.

When passkeys replace 2‑factor authentication, security and user experience are improved because the second factor is no longer required and users can authenticate with a single biometric step
d: 5.00Σ +3.112
AtomWeight
Passkeys render two‑factor authentication unnecessary1.125
Device‑provided security prevents users from leaking passkey secrets, even if they misunderstand how it works0.863
Phishing resistance of passkeys is achieved by scoping credentials to a domain0.813
FaceID or fingerprint biometrics can be used with passkeys to log in without remembering anything across all devices in the same ecosystem0.688
Chrome’s password manager and Apple’s ecosystem tightly integrate passkeys, enabling seamless use across a user’s devices0.625
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.-0.500
When a passkey is lost or a user needs to recover an account, most websites still provide a password or SMS code as a fallback, so the presence of these weak fallback mechanisms undermines the phishing‑resistance that passkeys claim to offer and means users maintain both strong and weak authentication methods simultaneously, adding complexity without eliminating the weak link.-0.500
Passkeys use biometric authentication (face‑ID or fingerprint scanning) that users recognize from Apple Pay or unlocking their phone, making the authentication experience familiar0.250
Magic links can serve as a fallback authentication method but carry serious security risks-0.250
Magic links should ideally be combined with two‑factor authentication when a shared secret is required for security-0.250
The WebAuthn protocol has had a few iterations and is ready for deployment0.250
Passkeys are tied to specific hardware or a vault that syncs across devices, so loss of that device can lock a user out.-0.250
A passkey can be considered equivalent to using a secure hardware token like YubiKey0.250

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

Criterion scInsecurePwd

Insecure single‑factor passwords increase the risk of compromise and weaken the security of user accounts

Team B
L: 5.000
Null: When a user relies only on a single password without additional security measures, this has no impact on the overall security of the account
d: 0.00

No linked atoms.

When a user relies only on a single password without additional security measures, the risk of compromise is high, thereby strengthening Team B's case
d: 5.00Σ +2.920
AtomWeight
Passwords are either clumsy to use or insecure0.900
Passwords without a second factor pose an unacceptable security risk, a risk also reflected in European regulation on banking logins0.787
Passwords stored only in a user’s head are typically weak or short or reused across multiple sites0.733
Two‑factor authentication often results in user experience problems; users may not understand it, become annoyed, or lose access to the second factor0.250
Password managers require users to copy and paste passwords, field recognition often fails, and the apps generate URLs that differ from the associated website0.250

Criterion scWeakFallback

Decreasing phishing resistance when a fallback password or SMS code is present strengthens Team B's case
