Passta is a fully offline password manager for KeePass (.kdbx) vaults. NO NETWORK, NO ACCOUNTS, NO TRACKING Passta contains no networking code at all. There are no servers, no sync service, no analytics, and nothing to sign up for. Your passwords live in a standard, encrypted KeePass file that you control — and they never leave your device unless you move them yourself. YOUR VAULT, WHERE YOU KEEP IT Open vaults in place from iCloud Drive, Dropbox, On My iPhone, or any storage that appears in the Files app. Passta remembers the location and reopens the file securely — it never makes hidden copies. EVERYTHING YOU EXPECT FROM A PASSWORD MANAGER • Open and edit KeePass vaults (KDBX 3.1 and KDBX 4) • Create new vaults directly on your iPhone or iPad • Unlock with Face ID • Fill passwords in Safari and other apps with AutoFill • Strong password generator • Find duplicate passwords • Organize entries with groups and auto-categorization • Key file support for stronger vault credentials OPEN FORMAT, NO LOCK-IN Passta uses the standard KeePass format supported by KeePass, KeePassXC, KeePassDX and many other apps on every platform. Your vault is yours: open it anywhere, today or in ten years. SERIOUS ABOUT SECURITY Vaults are protected by the KDBX 4 format's modern cryptography, including Argon2 key derivation. Biometric unlock keys are stored in the iOS Keychain, protected by Face ID. PRIVACY Passta collects no data. Its App Store privacy label is "Data Not Collected" — because there is literally nothing to collect.
