Sealfie uses advanced biometric verification and device attestation to ensure that validation requests come from real people using legitimate devices, making deepfake attacks virtually impossible.
Your biometric data never leaves your device. Sealfie uses on-device processing to create cryptographic proofs without storing or transmitting sensitive biometric information.
Unlike traditional 2FA that can be bypassed or spoofed, Sealfie provides cryptographic proof of human presence and device integrity, creating an unbreakable chain of authentication.
