'npm install' fails with Invalid authentication credentials

[doublespaces]

I have access to this Google Cloud Repository. I can view the code through the web browser. I also have google cloud sdk installed on this machine (Ubuntu) and I have ran gcloud init and logged into the associated account. When I run 'npm install' I get this error:

I can generate that new password, however I don't know where to put it. I have installed libsecret but I don't know how to get a password credential into the keyring.
