Ohtipi

iMessage OTP AutoFill in any browser on macOS

How's it work?

OhTipi relies on a local macOS app that looks for incoming texts with OTP codes in them. The macOS app copies those codes to your clipboard along with a notification. Everything happens locally and nothing is ever sent to a server.

Run for development

npm run install;
npm run dev;

💡 Note: During development, Full Disk Access permission must be granted to whichever app is running the npm run dev command (usually Terminal.app or Visual Studio Code.app). More info...

Find the important bits

• Main process
• iMessage service which queries the local sqlite database
• Modified fork of parse-otp-message, includes service list, service patterns and auth words. Particuarly difficult cases can otherwise be caught and handled within custom filters

Release flow

The following will only function with proprietary signing keys, etc. It is for internal use only.

Standard release

npm run install;
npm run release;

Setapp release

Open config.js and set { build.setApp } to true.

Make sure all .node native modules are compiled against the correct version of Node, Electron, etc. This project currently uses sqlite3, node-mac-permissions and setapp-nodejs-wrapper. The build script can be seen in ./build/build-setapp.sh. lipo is used to cross-compile .node modules for both arm64 and x64.

npm run build:setapp;

Distribution can now be found in /dist/mac-universal.

💡 Note: You may need to re-codesign the Universal app bundle:

codesign -fv --deep -s CBA[..................] ./dist/mac-universal/Ohtipi.app
