Required device app: Security Key
USB or NFC for registration and sign-in
For iPhone sign-in, use NFC with Chrome, Safari, or Firefox; the phone needs NFC.
Ledger lists Chrome on Android 14, with the Google Play system update dated March 1, 2024 or later. Firefox on Android is unsupported.
Passkeys stored on the key (resident or discoverable credentials) are not supported.
A compatible service and browser are required.
The device must also be registered as a security key with the website; installing the app alone does not register it.
Credentials from the older Ledger FIDO U2F app do not work with the Security Key app. Register the device as a new security key while keeping another working sign-in method.
Ledger documents restoring the Security Key app’s credentials on a new or reset Ledger set up with the same 24 recovery words. This does not cover resident credentials.
Keep another working sign-in method before relying on recovery.
