What harden_disable_ssh_password does on Aapanel
AI agents invoke harden_disable_ssh_password to trigger actions in Aapanel. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why harden_disable_ssh_password is rated High
This tool modifies the SSH daemon configuration to disable password authentication, enforcing key-only login. While it writes a configuration change, the primary effect is executing a system-level security policy change that affects access to the server. Misuse could lock out all users who don't have SSH keys configured, potentially causing irreversible loss of access.

harden_disable_ssh_password stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Aapanel, apply this rule, and every harden_disable_ssh_password call is checked against it from then on.
