Breaking through the architecture of HMI hardware and software, we freed HMI from its traditional combination with LCD panel and touch screen, and perfectly integrated HMI’s visual control into iPad with the powerful EasyBuilder project editor software. Not only do we inherit the advantage of traditional HMI and the motto of “Make Things Easy,” we also encourage infinite innovation in HMI technology and lead HMI into the cloud.

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.
