Security Authenticator is an all-in-one security application integrating identity verification (2FA), website and app password management, and asset management. It is dedicated to providing comprehensive, end-to-end protection for users' digital identities and assets. It strictly adheres to a privacy-first principle: All sensitive data (including 2FA keys, account credentials, mnemonic phrases, and private keys) is encrypted and stored only locally on the user's device and is never uploaded to any external server. The core security mechanism is based on Apple's official security framework. Access requires authentication via Face ID, Touch ID, or your master password, ensuring that even if the device is lost, others cannot view the content. Key features include: 【Offline Enhanced Security】 Sensitive data is securely stored offline, and the application can be used 100% offline. Even if our servers are attacked, we cannot access any of your data because we do not store it remotely. 【2FA Authenticator】 Supports the TOTP (RFC 6238) standard and is compatible with over 1000 mainstream platforms including Gmail, Facebook, Instagram, Twitter, Coinbase, and Binance. It supports quick QR code scanning, manual key input, and one-click verification code copying, improving login efficiency. 【Smart Password Management】 Includes a built-in high-strength random password generator, supporting password strength assessment and leak detection (based on a publicly available database of leaked data). It provides category tags, pinyin search, and autofill functionality in Safari and other apps, making account management more efficient. 【Asset Management】 Securely stores mnemonic phrases and private keys for over 20 mainstream blockchains, including Bitcoin (BTC), Ethereum (ETH), and Solana (SOL). All encrypted asset information is encrypted using AES-GCM and stored locally, ensuring private keys are never leaked. 【Sync Backup】 Achieves end-to-end encrypted synchronization via iCloud, enabling seamless switching between multiple devices. Data is always protected by Apple's security mechanisms. 【Native iOS Experience】 The interface is clean and smooth, with operations conforming to iOS design guidelines, balancing security and ease of use. The free version meets basic daily security needs; the pro version unlocks unlimited accounts, full password vault management, advanced sync features, and all other features. 【Subscription Terms】 Upon confirmation of your subscription, the fee will be charged to your iTunes account.

You can manage your subscription and turn off auto-renewal at any time in your Apple ID settings.
