More About Setting Default Usernames
If you’ve already created a scratch org, you can set the default username with the config:set command from your project directory.
More About Aliasing
Use the alias:set command to set an alias for an org or after you’ve authorized an org. You can create an alias for any org: Dev Hub, scratch, production, sandbox, and so on.
