Download

PQ Vault 2.0.1

Google-independent Android passkey manager: your keys are kept in an encrypted vault that you synchronize with your own WebDAV server (Nextcloud, ownCloud, Seafile or Apache WebDAV). PQ Vault does not manage passwords and can coexist with a password manager such as KeePassDX.

Manually installed beta: choose only your device architecture, verify its fingerprint in checksums.sha256, then temporarily allow installation from this source. The vault passphrase cannot be reset: use at least four or five random words and keep a secure backup.

Phone / tablet (ARM64)

beta debug

arm64-v8a APK for most recent physical Android devices. Android 11 minimum; Android 14 minimum for system passkey-provider integration.

Download APK

Emulator (x86_64)

beta debug

x86_64 APK intended mainly for Android emulators and the few compatible x86_64 devices. It is not suitable for an ARM64 phone.

Download APK

Recommended setup

1. Install the APK matching your architecture, then create the vault with a long passphrase backed up away from the device.

2. Create a dedicated WebDAV folder and use a revocable app password, never your cloud account’s primary password.

3. On Android 14 or newer, enable PQ Vault under Settings > Passwords, passkeys and autofill to use it in authorized apps and browsers.

Connectors

Android (connector)

beta

Android Companion beta APK: starts a local 127.0.0.1 connector to bypass WebDAV/Nextcloud CORS. Android/Play Protect warnings are normal in beta.
