Issue description

https://www.serverless.com/framework/docs/providers/aws/guide/credentials/#using-aws-access-keys

You instruct users to run:

serverless config credentials \
  --provider aws \
  --key AKIAIOSFODNN7EXAMPLE \
  --secret wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

passing secrets in the CLI is not secure! This logs the secret in plaintext in the users bash/zsh history! Instead, the command should be interactive taking in the input via stdin interactively so it's not logged into the shell's history.

I classified this as a bug because you're telling users to do something that is widely regarded as a bad security practice, and then you're referring to that as "the permanent" solution implying that it is secure or suitable for production environments.
