I've created a small application where you can sign up, login and store whatever "secret notes" you want to. They are going to be password protected, so well-kept. As log as you don't logout on purpose, the app will remember the last session and you'll stay in your account at runtime. Just give it a try.
Make sure you have installed the latest Python version.
git clone https://github.com/MirelaManta/MirelaApp
pip install -r requirements.txt
pyton main.py
