Android solutions for seamless sign-in across devices
summary
Block Store offers a simple API (integrate with fewer than 30 lines) to store encrypted auth tokens locally and optionally in cloud backup (end‑to‑end encrypted on Android 8+ with screen lock) so apps can restore zero‑touch sign‑in on new devices. OneTap creates token‑based, passwordless accounts and reports doubling partner acquisition/conversion. Passkeys follow FIDO/WebAuthn, sync via Google account, enable QR pairing and cross‑platform sign‑in with biometric 2‑factor‑in‑one ease. Block Store OneTap Passkeys
