Deepnet SafeKey vs Nitrokey Passkey

Deepnet SafeKey is a family of hardware security keys for passwordless sign-in and second-factor access to computers, web applications, and cloud services. Its listed authentication technologies include FIDO U2F, FIDO2 WebAuthn, OATH HOTP, OATH TOTP, and PIV Smartcard, allowing keys to act as FIDO authenticators, OTP tokens, or smartcards. The model range includes USB-A and USB-C keys, NFC models, and a card with contact ISO7816 and contactless NFC interfaces; several models have fingerprint protection. SafeKey contains no battery and requires no driver. Deepnet lists support for Windows, macOS, Android, and iOS. Its guides describe registering a FIDO2 key as a passkey for Google and Microsoft personal accounts. Windows 10 security-key sign-in requires an administrator to enable the setting through Microsoft Intune and allow FIDO2 keys as an authentication method. Deepnet says its FIDO authentication is based on open standards from the FIDO Alliance. Technical guides and online chat and callback contact options are listed.
