Hi @george_4088,
That is correct, but a brute-force attack wouldn't succeed unless an administrator used something silly like admin for their username and password for their password. You could just as easily integrate with an LDAP/Active Directory server, which will add timeouts and account lockouts to make it impossible to "crack" in our lifetime. SAML is fine too.
My point is that it's like 1000 times more likely that the API Key used to publish those Chocolatey packages would be exposed in logs, configuration files, etc. That's the attack surface you want to be careful of.
Cheers,
Alana
