Password managers help people store and fill credentials. Secret brokers give autonomous agents narrowly scoped execution access, bind it to purpose and approval, redact evidence, block memory promotion, and prove when access expires.
A password manager is optimized for a person who sees the destination and initiates the fill. A secret broker is designed for software that plans, requests approval, executes tools, preserves evidence, and may continue acting after the original interaction.
A password manager asks whether the user can access a credential. A broker asks whether this agent, tool, origin, session, action, amount, purpose, approval, and time window authorize one use. Super can provide the phone-native approval surface while the raw value remains outside the conversation and planning model.
Stores credentials, verifies the user, suggests matches, and fills into recognized applications or sites.
Issues purpose-bound grants to agents and resolves values directly inside trusted execution tools.
Encryption, identity, recovery, rotation, origin awareness, audit, and protection against phishing.
Pair a broker with a computer-use cache so action proof uses stable placeholders rather than exposed secrets.
Use a text-message AI assistant to approve once, narrow scope, edit, deny, or request an explanation.
Choose based on who initiates the action and how much autonomy follows.
Password manager: a person actively browsing or using an application. Secret broker: an agent planning and executing on the person’s behalf through browser or API tools.
Password manager: authenticated user plus application or site matching. Secret broker: user, agent, tool, origin, session, action, purpose, amount, recipient, approval, and expiration.
Password manager: autofill, copy, reveal, passkey, or application integration. Secret broker: short-lived token resolved directly by a trusted execution adapter.
Password manager: usually outside AI planning concerns. Secret broker: explicitly prevents raw values from entering prompts, transcripts, traces, evaluations, or model-side storage.
Password manager: login history, security events, and vault audit. Secret broker: redacted screenshots, action traces, approval receipts, tool results, expiry, memory impact, and repair.
Password manager: people managing accounts and credentials. Secret broker: personal agents buying, booking, logging in, handling private records, or completing multi-step delegated work.
Hover across the lanes to see what changes when the operator is an autonomous agent.
Both products protect credentials and private values at rest.
The broker exposes placeholders and policy metadata to the model.
The broker binds human intent to the exact delegated action.
The tool receives the raw value while the model and replay do not.
Password managers prove the user can access a secret. Secret brokers prove an agent may use it for one bounded purpose without learning it.
Use this checklist when extending credential infrastructure to personal AI agents.
Every request identifies the agent, planning runtime, execution tool, user, and active session.
Grants include destination, field, action, amount, recipient, purpose, approval, and deadline.
Raw values never appear in prompts, transcripts, traces, evaluations, or long-term memory.
Screenshots, OCR, DOM, videos, logs, and support exports use stable placeholders.
Tokens, sessions, caches, evidence, and memory are tested after denial, expiry, or deletion.
If work feeds an AI website-building workflow, placeholders persist into drafts, forms, metadata, analytics, and deploy logs.
Many teams will keep their password manager and add a broker layer for autonomous execution.
Yes, if it adds agent and tool identity, purpose-bound grants, explicit approval, short-lived execution tokens, evidence redaction, memory controls, and repair workflows.
No. Passkeys remain a strong authentication mechanism. The broker governs whether and how an agent may invoke the authentication flow for a delegated purpose.
Prefer direct execution adapters, passkeys, OAuth, or scoped API credentials. Copying exposes values to more interfaces and increases replay and memory risk.
Expire the grant, redact evidence, record the result, block memory promotion, and offer rollback or repair when the action fails.
Super can provide the phone-native approval and clarification lane for consequential delegated actions.

Password managers protect credentials for people. Secret brokers extend that protection into agent planning, approval, execution, evidence, memory, and repair.
