Passkey-based wallets with 1-line integration is the UX breakthrough crypto has been waiting for since MetaMask. Face ID and fingerprint auth eliminates the seed phrase entirely — no more 12-word backup, no more hardware wallet dongles, just biometric proof you are you. The security model is elegant: passkeys are device-bound, phishing-resistant, and backed by Apple/Google cloud sync. For AI agents, this matters because scoped passkey delegation could replace raw private key access with hardware-attested, biometric-gated permissions. The 1-line SDK integration means every app becomes a wallet — which means every AI agent framework becomes a wallet. Tempo is building the on-ramp for the next billion users who will never know what a seed phrase is.
