1Password is an excellent place to securely manage passwords, API keys, and other credentials. Keep your personal credentials separate and create a dedicated vault for your agent, giving it access only to the secrets it needs through a service account.

Instead of pasting passwords or API keys into chats, prompts, scripts, or configuration files, the agent can retrieve credentials securely when needed. The agent may still access the secret while using it, but it doesn’t need to store it in its memory, chat history, or project files. Access can also be centrally controlled and revoked at any time.
