Simple OTP is a free secure OTP generator that is usable across sites and devices.
And… it’s an excuse to learn flutter/dart
With the Authy desktop application going away, there is a need for a simple but secure OTP generator that is not tied to the company with the 2FA requirement, like google or Bitwarden. This was designed to be a minimalist project but with the ability to import/export.
Uses flutter/dart so the project will work across all major devices. Starting with Linux/Android.
The application has a basic flow. Unlock your database, add/remove authentication secrets, and generate code for secrets you select. Codes are regenerated when the current one expires. Can add to the clipboard.
There is no cloud save. You can export/import files. Some point in the future I may do a device/device communications to sync devices.
Your authentication secrets are encrypted with AES/GCM using a 256-bit key derived from your password.
