Core Advantages

Security, Simplicity & Reliability

Focused on cryptographic fundamentals. Zero commercial clutter, giving you absolute peace of mind for your credentials.

🛡️

Local Offline Computation

Strictly conforms to the RFC 6238 industry standard. Codes are computed in real time by your device CPU, functioning flawlessly even in airplane mode with secret keys never leaving your hardware.

🚫

Zero-Tracking Guarantee

Never integrates third-party marketing SDKs, user analytics, or cross-platform tracking. Your sensitive digital identities belong only to you, never shared or monetized.

☁️

End-to-End Encrypted Sync

Seamless multi-device cloud synchronization over TLS 1.3 channels. High-grade ciphertext storage prevents asset loss when switching or recovering devices.

👆

Biometric App Lock

Protected by system-native Face ID and Fingerprint authentication. Raw biometric credentials are validated directly by the operating system secure hardware enclave (TEE).

📷

Instant Scan & Migration

Rapidly detects and parses otpauth:// QR codes. Easily import accounts from Google Authenticator and other compliant tools with encrypted backup support.

⚡

High-Performance Backend

Powered by an independent native Bun + PostgreSQL backend for sub-millisecond API responses and fully isolated dedicated storage.

Data Privacy & Compliance

Strict Data Minimization & Privacy-First Principle

Two-factor authentication secrets are highly sensitive digital assets. Both in the mobile application and our backend services, LazyCoffee always puts your security and privacy first.

  • Zero Sensitive Profiling: We do not collect real names, government IDs, location, or contacts.
  • Camera Exclusively for QR: Camera is requested only when actively scanning QR codes, never retained.
  • Complete Data Rights: Export encrypted backups, clear local storage, or permanently delete your cloud account at any time.
App Privacy Declaration Excerpt
"LazyCoffee TOTP is dedicated to safeguarding your account security and privacy. The application collects only the absolute minimum dataset required to maintain service operation. The TOTP algorithm strictly conforms to the RFC 6238 industry standard, and dynamic verification code computations occur in real time locally on your device."

End-to-End Pipeline

Cryptographic Architecture

From QR code scanning to local secure persistence and incremental cloud sync.

STEP 01

In-Memory Scan

Decodes otpauth:// structure strictly in protected RAM without writing to media libraries.

STEP 02

Sandboxed Storage

Credentials are encrypted in local OS sandboxes and tied to hardware Keystore / Keychain.

STEP 03

Local HMAC Codes

Computes periodic 30-second 6-digit TOTP tokens offline on the device CPU without network leaks.

STEP 04

TLS 1.3 Sync

Optional cloud sync runs over strictly enforced modern TLS 1.3 into dedicated isolated databases.

FAQ

Security & Usage FAQ

What is TOTP? Why is it more secure than SMS verification?

TOTP (Time-based One-Time Password) is an open international security standard. Unlike SMS codes, it does not rely on cellular networks or carrier gateways, providing complete immunity against SIM swapping and cell tower interception.

Can I generate codes while in airplane mode or without an internet connection?

Absolutely! TOTP calculations rely solely on your device's internal system clock and the stored secret keys. No network connectivity is required, working seamlessly on planes or in subterranean locations.

Are my secret keys uploaded or exposed to third parties?

Never. LazyCoffee TOTP integrates zero marketing or analytics SDKs. Even when cloud sync is enabled, credentials in transit are encrypted via TLS 1.3 and isolated from any third party.

How do I safely migrate my accounts when upgrading to a new phone?

You can sign in to your LazyCoffee account to restore from the encrypted cloud, or export an encrypted backup file from the app settings to import on your new phone.
