@CameronMacG and @dgscwhite I need your assistance reviewing this please. Can you do the following to test this works:

1. Clone the repo (if you have not already)

git clone https://github.com/mjennings061/viking-log-keeper.git

2. Navigate into the directory:

cd viking-log-keeper

3. Checkout this branch

git checkout 36-store-credentials-using-keyring

4. Install the app (ensure you have python installed). The . is important below

python -m pip install --upgrade .

5. Run the dashboard

viking-dashboard

6. Enter in the database credentials from your email (it will auto prompt you)
7. Go to the dashboard http://localhost:8501
