I really need your help to finalize the uploading of the piwallet script (https://github.com/johnathanmartin/piWallet/).
I installed my Daemon Bitcoind and it works fine when I try it with the command "bitcoin-cli getinfo".
But I have a big problem, on the Home Page below in Screenshot, we see the Connection Information as "Username", "Password", "2FA Authentication".
So I filled in the Username and Password fields correctly but not knowing what I was going to upgrade to the 2FA Authentication (field), I click on the Button Log in so I left the 2FA Authenticicator field blank to put.
But just after clicking on Log In, I get Error 401 from the Screen Capture below:
According to the developer's documentation (https://github.com/johnathanmartin/piWallet/wiki/API) on github the Error 401 indicates that the Api Key is incorrect. Where can I find this API key and how to insert it in the script so that it is correct and that everything works normally
Thank you for helping me please.
