SecureKit is a private encrypted vault for iPhone that keeps sensitive information on your device. Store passwords, two factor authentication codes, private photos, identity documents, sensitive notes, and audio recordings together in one protected place.

SecureKit does not require an account and does not use a cloud vault or synchronization. Vault content is encrypted locally with 256 bit AES GCM encryption. Access is protected by Face ID or the device passcode, and the vault key is protected by the iOS Keychain.

Organize items into custom groups, search across the vault, restore items from Recently Deleted, receive document expiry reminders, and choose when the app locks. Shake to Lock provides an instant physical gesture for securing your vault.

Encrypted backup and restore lets you create your own password protected backup file. The recovery password is never stored, and the vault key is never written to the backup.

The core vault is free. SecureKit Premium unlocks private photo imports, two factor authentication codes, and encrypted backup creation for $2.99 monthly or $29.99 yearly.

Authenticator features and specs

  • Open Source
    Authenticator is open-source, which means the source code is available for review and contributions by the community. This increases transparency and security, as bugs and vulnerabilities can be identified and addressed more quickly.
  • Privacy-Focused
    The app doesn't require users to create an account, and it doesn't store any data in the cloud. This significantly reduces the risk of data breaches and ensures user data remains private.
  • Simple User Interface
    The app provides a clean and intuitive interface, making it easy for users to manage their two-factor authentication (2FA) codes without confusion.
  • Local Storage
    Authenticator stores codes locally on the device, which enhances security by eliminating the need to transmit sensitive information over the internet.
  • Cross-Platform Support
    The app is available on both iOS and Android, providing flexibility for users who switch between different mobile operating systems.

Possible disadvantages of Authenticator

  • No Cloud Backup
    Since the app stores data locally and doesn’t support cloud backup, users may lose their codes if they lose access to their device or accidentally delete the app.
  • Manual Setup
    Users need to manually add their accounts, which might be less convenient compared to some other 2FA apps that offer QR code scanning and automatic account import features.
  • Limited Features
    Authenticator focuses on core 2FA functionality and lacks some advanced features found in other 2FA apps, such as password management or integration with password managers.
  • No Multi-Device Sync
    The app doesn’t support synchronizing 2FA codes across multiple devices, which can be inconvenient for users who rely on multiple devices for their work or personal life.

SecureKit features and specs

  • On device encryption
    256 bit AES GCM encryption with the vault key protected by iOS Keychain
  • Passwords and 2FA
    Store passwords and two factor authentication codes in the same private vault
