flowtext.io

flowtext.io is a MacOS application designed to eliminate the manual work of handling two-factor authentication codes. It runs on your Mac and monitors incoming SMS messages through iMessage. When you receive a text containing a verification code from services like your bank, Gmail, Instagram, or GitHub, the app automatically finds the numeric code, copies it to your clipboard, and shows you a notification. This means you can simply paste the code into the login field instead of switching apps to find and copy it yourself.

The tool works entirely on your local machine. It doesn't send your messages or any data to external servers, which addresses privacy concerns. The setup is straightforward: you download and install the app, and it begins working in the background. It uses the same SMS access technology built into MacOS and iOS, making the detection process reliable for standard authentication messages.

This app is most useful for anyone who logs into multiple services protected by SMS-based two-factor authentication on a regular basis. It saves a few seconds with each login, which adds up significantly for developers, professionals, and security-conscious users. The core benefit is convenience—turning a multi-step, interruptive task into a single paste operation.
