Two-factor codes, everywhere you sign in. Jumpstash is a beautifully native authenticator for the entire Apple ecosystem. Glance at your wrist, AutoFill in Safari, scan on your phone - your codes are with you wherever you log in. WHAT MAKES JUMPSTASH DIFFERENT - APPLE WATCH COMPLICATION Your most-used verification code, right on your watch face. Inline, circular, or rectangular — each with a live 30-second countdown ring. No more pulling out your phone. - SAFARI & SYSTEM AUTOFILL Tap a verification-code field in Safari or any iOS 18+ app, choose Jumpstash, done. Zero copy-paste. - MAC MENU-BAR APP One click in the menu bar, see your code, copy, dismiss. No System Settings detour. - FACE ID & TOUCH ID LOCK Codes hide behind biometric authentication. Backgrounding the app instantly draws a privacy curtain — no peeking from the app switcher. - LOSSLESS BACKUP & PORTABILITY Export every code as JSON for a perfect restore, plus standard otpauth:// URIs and QR codes. Your codes are yours — take them anywhere, anytime. - iCLOUD KEYCHAIN SYNC Your codes follow you across iPhone, iPad, Mac, and Apple Watch automatically — synced by Apple, end-to-end encrypted. - PRIVATE BY DEFAULT No accounts. No servers. No telemetry. Jumpstash never sees your secrets — they live in your iCloud Keychain, protected by Apple's own security model. DESIGNED FOR YOU IF… > You 2FA across dozens of services every day > You want a glanceable code on your wrist without opening your phone > You care about export portability and don't want to be locked into one ecosystem > You prefer a focused, single-purpose app over a sub-feature buried in another tool WHAT ABOUT APPLE PASSWORDS? Apple's Passwords app does TOTP, and it does a good job. For most people, it's enough. Jumpstash exists for users who treat 2FA as a daily ritual: a watch complication for instant access, true export so your codes are never locked behind a one-way iCloud door, and a UI built around codes as the first-class experience instead of a sub-feature. WHAT'S INSIDE - QR code scanner with one-tap import - otpauth:// URL handler (tap a link in Messages, Mail, or any app to import) - Manual entry with a live preview that animates as you type - Edit any code (name, issuer, or secret) without losing the entry - Delete with confirmation - Global search and Contacts-style #-A-Z index with drag-scrubbing for fast navigation across many codes - Tap any code to copy it - Live countdown ring on every card - Support for SHA-1, SHA-256, SHA-512 algorithms - Support for custom periods (30s, 60s) and digit lengths (6, 7, 8) PRIVACY & SECURITY Jumpstash uses Apple's iCloud Keychain as its sole storage and sync mechanism. Your TOTP secrets are encrypted end-to-end by Apple, available only to your devices. No analytics SDKs. No tracking. No accounts to create. No servers to trust. Made by Danger Close Security Co.
