RabbitKey keeps your passwords encrypted on your device — not on someone else's server. Built for people who take security seriously. END-TO-END ENCRYPTION Every entry is encrypted with XChaCha20-Poly1305 before it ever touches storage. Only your master password can unlock your vault — your data stays on your device, and we never see it. BIOMETRIC UNLOCK Unlock your vault instantly with Face ID or Touch ID. Your biometric data never leaves the device. FREE CLOUD SYNC Keep your vault in sync across iPhone, iPad, and Mac through iCloud, Google Drive, or your own WebDAV server — free, no Pro required. You choose where your data lives — or keep it fully offline. SYSTEM AUTOFILL RabbitKey integrates with iOS AutoFill so credentials appear right above the keyboard — in Safari, in apps, anywhere iOS supports autofill. ONE-TIME CODES (OTP) WITH AUTOFILL Store your two-factor authentication secrets next to the matching login. RabbitKey generates the rolling 6-digit code and autofills it straight from the keyboard — no app switching. OTP secrets are encrypted just like everything else. STRONG PASSWORD GENERATOR Generate high-entropy passwords on demand. Tune length and character classes to fit any site's rules. PASSWORD HEALTH Surface weak and reused passwords before they become a problem. RabbitKey scans your vault and flags entries that need attention. IMPORT IN SECONDS Migrating from another password manager or browser? Import existing passwords from a CSV file in a guided, step-by-step flow. DEVICE MIGRATION Moving to a new iPhone or iPad? Transfer your vault directly via QR code — no cloud, no account required. MULTIPLE VAULTS Keep work and personal credentials separate with independent vaults, each with its own master password. TRASH & RECOVERY Deleted something by accident? Entries stay in Trash for 30 days before permanent removal. FREE vs PRO — ONE-TIME PURCHASE, NO SUBSCRIPTION Free: up to 100 entries with full XChaCha20-Poly1305 encryption, biometric unlock, AutoFill, cloud sync (iCloud / Google Drive / WebDAV), password generator, password health, tags, multiple vaults, QR device migration, CSV import, trash recovery, and offline use. Pro (one-time purchase): unlimited entries plus one-time codes (OTP) with autofill. No subscriptions. No ads. No analytics SDKs. A password manager that respects your privacy.

The call
