Isn't it weird that we put credentials in the environment?
Almost every program that we run has access to the environment, so nothing stops them from curling our credentials to some nefarious server.
Why don't we put credentials in files and then pass them to the programs that need them? Maybe coupled with some mechanism that prevents executables from reading any random file except those approved.

I have a rule that credentials in environment variables are to only ever be loaded as needed via some sort of secrets manager, optionally adding a wrapper script to do so transparently.
The whole point of passing secrets as environment variables is to avoid having things in files in plain and in known locations easy to scrape up by any malware.
Now we have people going full circle and slapping those into a
.envfile.But how do you authenticate to your secret manager? How do you prevent evil scripts from also doing this?
I type my password, or on the work MacBook, TouchID. I'd imagine yubikeys would do too.
You could decrypt a GPG key-based file to do that.
I'd be very thankful for an example of your setup. I'm using Bitwardern for browser-related password management, but for convenience scripts I load the credentials as env vars at login through
.bash_profile😅Basically just have each sets of credentials in a script, and whenever you need to use something that needs a key, you source the script you need first.
Then each of those scripts are something like
thank you!
