PassVault
A secure, lightweight, and offline password manager for Android built with
Kotlin.
[](https://apt.izzysoft.de/packages/com.jksalcedo.passvault)
PassVault is a secure, lightweight, and completely offline password manager for Android. It empowers
you to store and manage your credentials locally with military-grade encryption (AES-256), ensuring
your data never leaves your device.
Built with a focus on privacy and usability, PassVault features a modern Material Design interface,
robust import capabilities (seamlessly migrating from KeePass and Bitwarden), and advanced security
options like biometric login and encrypted backups. Whether you're organizing passwords with custom
categories or generating strong credentials, PassVault keeps your digital life secure and
accessible.
