Developer Tools: open-source Cloud Credentials management

What are the open-source options to manage system Cloud credentials (Like AWS and Azure)?

• AWS Vault (https://github.com/99designs/aws-vault) -> CLI tool to manage AWS credentials

• Leapp (https://github.com/Noovolari/leapp) -> Multi-Cloud Desktop App that Manages session tokens and Access keys on AWS and Subscription and Tenants in Azure

• AWSume (https://github.com/trek10inc/awsume) -> manage session tokens and assume role credentials in AWS

Any other tool?
