Error during setup of component usps

Configuration
1

I had to rebuild my HA on RPi and trying to setup USPS sensor

I setup the following in configuration.yaml file:

    usps:
      username: !secret usps_username
      password: !secret usps_password

Every time I restart my RPi, I see the following error:
Capture

When I check log file, there is an error:

    Error during setup of component usps

Can someone help?

just so you know the usps component has been broken for a few months. USPS changed their login authentication and the current component fails to login. Someone has made a workaround that uses the emails sent with the same info, but you have to load a custom python script.

I did not know, thank you.
