Password Safe

Can you trust a password manager that never connects to the internet?

For anyone managing dozens of online accounts, the central dilemma is always the same: convenience versus security. Most password managers store your credentials on remote servers, which introduces a vector for potential breaches, server-side vulnerabilities, or third-party access. Password Safe, developed by Robert Ehrhardt, takes a fundamentally different approach—it keeps everything offline, stored directly on your Android device. This is not a cloud-synced vault with a web interface; it is a self-contained, local application that functions as a digital safe deposit box for your login credentials.

The core mechanic is straightforward. Upon first launch, you set a master password that encrypts the entire vault. Every subsequent session requires this single key, and the app provides no recovery mechanism—if you forget it, the data is permanently inaccessible. This is a deliberate design choice that prioritizes absolute security over user convenience. There is no "reset password" link, no email-based recovery, and no cloud backup. What you control is what you keep.

Features and functional analysis

Once inside the vault, the interface presents a clean, hierarchical structure for organizing credentials. You can create custom categories—such as Banking, Social Media, Work, or Entertainment—and assign individual entries to these groups. Each entry stores not only the username and password but also optional fields for URLs, notes, and custom labels. The app supports manual entry, bulk import, and export functionality, though the export is limited to local file formats.

A significant addition in version 9.2.1 is the integrated password generator. This tool allows you to create randomized strings based on user-defined parameters: length, inclusion of uppercase letters, lowercase letters, digits, and special characters. The generator can produce cryptographically strong passwords that are resistant to dictionary and brute-force attacks. You can access this generator directly from within the app or, more conveniently, via a widget placed on your home screen. The widget eliminates the need to open the full application every time you need a new password for a registration form.

Security measures are extensive and notably restrictive. The application explicitly blocks internet access at the kernel level—it cannot send or receive data over Wi-Fi or mobile networks. There is no telemetry, no analytics, no crash reports, and no login requests to external servers. Additionally, the app prevents other applications from taking screenshots while the vault is open. This means that any background process or malicious software attempting to capture your screen will receive a blank frame. The vault also auto-locks after a customizable period of inactivity, requiring re-entry of the master password.

The PRO version, available through an in-app purchase, introduces several advanced features. These include support for biometric authentication (fingerprint or face unlock), encrypted backup files that can be stored on external SD cards, and a more granular permission system for shared devices. The PRO tier also removes the optional donation prompt and unlocks theme customization options, though the core functionality remains identical between the free and paid versions.
