Synced Passkeys are
Sinking Security
Synced passkeys can be socially engineered, aren't device-bound, and aren't SCA-compliant. While better than passwords, they are not multi-factor and have created a sense of false security.
Synced Passkeys are
Losing control of your security
Synced Passkeys are not multi-factor authentication — they create real risk and regulatory exposure.
Exportable means exposed
Passkeys that sync or transfer break the chain of trust.
Synced ≠ device-bound
You can’t prove possession when credentials float.
Shared trust
is no trust
is no trust
Relying on Apple or Google isn’t zero trust — it’s blind trust.
Compliance gaps widen
Synced passkeys can’t meet PSD2, SCA, or audit requirements.
Patented Cryptography
Authentication you can prove — every time
Most industry experts agree that properly binding passkeys to the device upon which they were created delivers a trusted Passkey. Ideem’s Zero-Trust Secure Module (ZSM) delivers device bound passkeys that cryptographically verifies the possession of the original device and the biometric/PIN of the user.
Device-Bound ZSM
Passkeys only work on the device they were created on, upon first use, invisibly and automatically.
Biometric + possession
Every login requires biometric or PIN, completing true 2FA.
No Third Parties
ZSM produces a signed credential that proves device and user binding, verifiable by relying parties without needing to trust upstream platforms.
