Passkey Metadata
Samsung Pass
According to Samsung documentation ( source), Samsung Pass creates synced passkeys which are available on other devices where Samsung Pass is installed.
During testing on 2024-09-05, it was observed that passkeys created in Samsung Pass return the backup eligible flag as false, signaling a device-bound passkey.
Test device details:
- Galaxy S22
- Android 14 (UP1A.231005.007.S901USQS6EXG8)
- One UI 6.1
- Samsung Pass 4.4.02.7
