LastID
AI Agent Identity

Give your AI agents an identity, real limits, and a record you can trust.

Your agents run tools, hold API keys, and spend money. LastID gives each one a verified identity, lets it use your keys without ever seeing them, follows the rules you set, and keeps a record of everything it did.

How it works

Set up an agent in three steps.

Approve it once, decide what it can touch, and watch what it does. Works with the agent tools you already run.

01Give it an identity

Approve the agent in your LastID wallet. It gets its own verified identity, separate from yours and from every other agent.

02Decide what it can touch

Share the keys it needs, which it uses but never sees, and turn on the rules you want it to follow.

03See everything it did

Watch each agent in a clear, tamper-proof record. Know which agent acted, what it touched, and when.

Portable

One identity, rules, and memory that follow your agent.

Set it up once. As your agent moves between sessions and tools, it keeps the same identity, follows the same rules, and remembers what it learned. You stay in control the whole time.

Credentials

Let agents use your API keys, not hold them.

Agents need keys for Stripe, GitHub, and the rest. Pasting them into a file or the chat means the key sits there forever and leaks the moment something goes wrong.

Today

You drop an API key into a .env file or the prompt so the agent can call the service. Now the key lives in plain sight, and any slip or bad instruction can leak it.

The key has full access, all the time, and the agent can read it straight out of context.

With LastID

You share the credential once. When the agent makes a call, LastID adds the key at the moment of the request and the agent never sees it. Each use is single-shot and short-lived.

Every use is rate-limited, scoped, and recorded. No key sits at rest waiting to leak.

Guardrails

Set guardrails your agent can't talk its way around.

A clever prompt can talk an agent into deleting data, running a sketchy install, or touching production. Good intentions are not a control.

Today

You tell the agent the rules in a prompt and hope it listens. One persuasive instruction later, it runs the command anyway.

Instructions in a prompt are suggestions. Nothing stops the agent from ignoring them.

With LastID

You set the rules once and sign them. The agent blocks, warns, or rewrites the matching actions on every step, even with no connection, and cannot turn the rules off by editing a file.

See which rules fire over time, and start from ready-made packs for common risks.

Accountability

Prove what every agent did.

When agents run real work, you need a clear answer to a simple question: did the agent change that, leak that, or spend that, and which agent was it?

Today

You have scattered logs across tools, if you have anything at all. After an incident you piece together what happened and hope the logs were not edited.

Plain logs can be changed or deleted, and they rarely tie an action back to a specific agent.

With LastID

Every action lands in a tamper-proof record tied to that agent's identity. You can see which agent acted, what it touched, and when, and confirm the record was not altered.

Built for audits and incident response. You choose what gets recorded.

Least privilege

Give each agent only what it needs.

Most agents run with the same broad access you have. If one is tricked or goes wrong, it can reach everything.

Today

The agent inherits your full access and a pile of standing keys. One bad moment puts all of it at risk.

Broad, always-on access turns a single mistake into a big one.

With LastID

Each agent gets a bounded identity and can only do what you allowed. It refuses anything else, and it holds no keys at rest.

See exactly how little access your whole fleet holds, measured in seconds, not days.

Memory

Give your agent a memory you control.

Agents forget what they learned the moment a session ends, or scribble notes into files you cannot see or trust. Useful knowledge gets lost or goes stale.

Today

Your agent starts over every session, or keeps notes in scattered local files. It repeats questions, loses context, and you have no say in what it saved.

Notes in a file are not reviewed, not shared, and can say anything.

With LastID

Your agent remembers across sessions and tools, and finds the right memory by meaning, not just exact words. You review what it wants to keep, and the facts you set always come through.

Approve, edit, or remove what your agent remembers, anytime. It travels with the agent everywhere it works.

Start with one agent.

Set it up in a few minutes. Add the rest of your fleet when you are ready.

Get started

What you get.

Keys they use, never hold

Your agents call the services they need without ever seeing the key. Nothing sits at rest, so there is nothing to leak.

Rules they cannot ignore

The limits you set are enforced on every action, even offline, and cannot be switched off by editing a file.

A record you can trust

Every action is tied to a verified agent and written to a tamper-proof record you can check at any time.

Also from LastID

The same identity protects your people.

Verify a real person in seconds, on any channel. Stop callback fraud, deepfake approvals, and account-recovery attacks.

Give your agents an identity today.

Set up your first agent in minutes. See the keys it can use, the rules it follows, and the record of everything it does.
