Proposed change

As part of our ongoing research on Python dependency management we noticed a potential improvement in your project’s dependency management.

Specifically, the dependencies certifi and keyrings.alt are specified as a requirement in the requirements.txt file, when in reality they are not needed.

certifi, introduced in 9539a2c is a transitive dependency of requests.
This PR removes it from requirements.txt to let pip manage it automatically, which helps keeping the dependency list clean.

keyrings.alt, introduced in 9dcbd46 is not used in the project.

Hope this is helpful!

Best regards
