Authnkey vs Port Authority
Side-by-side comparison of two open source alternatives
Authnkey
Authnkey is a credential provider that lets you use FIDO2 security keys (like YubiKey, SoloKey, Nitrokey, or Token2) for passkey authentication on Android. Android's built-in WebAuthn support has a significant gap: it does not support CTAP2 over NFC. This means you cannot use PIN-protected passkeys or discoverable credentials with NFC security keys — you're limited to basic U2F tap-to-authenticate. Authnkey fills this gap by implementing the full CTAP2 protocol. The app registers as a credential provider, so any app or browser that supports the Android Credential Manager API will offer Authnkey as an option when passkeys are requested. This also works on devices without Google Play Services, since Authnkey implements the CTAP2 protocol directly rather than relying on Google's FIDO2 API. Supported features: - Passkey creation and authentication - PIN verification - Discoverable credentials - Multiple accounts per site - NFC and USB transports No root required.
Port Authority
A handy systems and security-focused tool, Port Authority is a very fast port scanner. Port Authority also allows you to quickly discover hosts on your network and will display useful network information about your device and other hosts.One of the fastest port scanners with host discovery on the market! Host discovery is typically performed in 3 seconds. If the device you’re scanning drops packets, it takes less than 10 seconds to scan 1000 ports. If the device you’re scanning rejects packets, it takes about ~30 seconds seconds to scan all 65,535 ports!Port Authority has no ads and will never have ads. It requires extremely limited permissions since it only needs to interact with your network. The internals are designed to take advantage of today’s modern phones with multiple cores to ensure you can scan your network as fast as possible.
