But now you have the only credential, the REPO_TOKEN in plaintext in your .git/config file. That’s even worse.
Edit: typo
That’s how a lot of tools work. Your maven password is in .m2/settings.xml
Your ssh private key is in .ssh/id_rsa
The only person with access to these files should be you. If anyone else does then your machine is compromised
we’re talking about a hypothetical one-off situation on a computer that isn’t yours though; right? That happens from time to time, and an authentication process that requires you to persist your auth information on disk carries some extra risks. You need to remember to delete it when you’re done.
