Keyring Name should be configurable for Linux #1293
Description
Is your feature request related to a problem? Please describe.
Yes, I want to use my default login keyring on Linux.
Describe the solution you'd like
Make the following an env var lookup which falls back to the constant value:
aws-sso-cli/internal/storage/keyring.go
Line 40 in 919bc03
Describe alternatives you've considered
Using file as SecureStore
Additional context
It is unpractical in my case to have multiple keyrings to unlock. I want to keep everything in the default one.
