Obsidian Vault is a beautiful, private place for your passwords — designed to feel as serious as it is. Your data is encrypted on your device with strong AES-256 encryption and unlocked with a 4-digit passcode or Face ID / Touch ID. There are no accounts to create and no servers involved — the developer never sees your data. Need your passwords on a new phone? Turn on optional Cloud Sync and your encrypted vault is backed up to your OWN Google Drive. Sign in on a new device and restore in seconds. Nothing is stored on anyone else's servers. One simple, one-time purchase. No subscriptions. No ads. No tracking. FEATURES - Strong encryption — AES-256-GCM, keys derived with Argon2id - Unlock with a passcode or Face ID / Touch ID - Password generator — strong random passwords and memorable passphrases, with strength and crack-time estimates - Built-in 2FA codes (TOTP) with a live countdown - Vault Health — spot weak and reused passwords at a glance - Bring-your-own-cloud backup to your private Google Drive folder - Browse and restore previous backups - Four gorgeous themes — Obsidian, Daybreak, Emerald, Carbon - Fast search, pinning, and clean organization - Clipboard auto-clears after copying; auto-lock when you leave the app PRIVATE BY DESIGN - No servers, no analytics, no ads, no third-party tracking - Cloud backups go only to your own Google Drive (a private app folder) - Everything is encrypted before it ever leaves your device Important: if you enable cloud backup, protect your Google account — anyone who can access it could reach the backup. If you lose access to both your device and your Google account, your data cannot be recovered, because we never hold it.
