Monica

A local-first password vault that combines Bitwarden and KeePass, available on Android and in the browser.

Monica puts local storage first, helping you manage account passwords, two-factor authentication codes, private notes, and sensitive attachments across Android and the browser.

Features

- Local encrypted vault: login credentials, bank cards, identity information, private notes, and attachments. - Dual-ecosystem aggregation: Bitwarden API and sync capabilities on Android, plus KeePass (.kdbx) read and write support. - Optional sync and backup: cross-device data flow through your own WebDAV infrastructure. - Built-in TOTP: manage passwords and two-factor codes in the same app. - Aggregated import: KeePass migration and Bitwarden-compatible import. - Smart search: find credentials quickly by title, domain, or tag. - Biometric unlock: use system-level biometrics for security and convenience.

MDBX local database format

MDBX is Monica's local-first encrypted vault format. It is not a simple password table but a database format built around nested folders, attachments, commit history, conflict detection, tombstone deletion, snapshot recovery, and Tiga safety mode.

If you want to integrate MDBX into another client, read the MDBX workspace documentation and the MDBX client integration guide.

Note

Due to system compatibility issues, Monica for Android currently cannot create Passkeys on some Xiaomi HyperOS devices.
