Sign-in · Agent authorization · MCP native

One identity for you.
Safe access for your agents.

Create one Identvia ID and sign in to any app that supports it. When an AI agent needs to act for you, Identvia gives it a short-lived, narrowly scoped pass — never your password — and asks you before anything sensitive happens.

For people

Sign up once. Walk into everything.

No new password for every app. No agent holding your login. One dashboard controls every app, every agent and every permission connected to your identity.

One ID, every app

Any developer can add "Sign in with Identvia" in minutes with our drop-in button or PHP, JS and WordPress-friendly integrations. Your profile travels with you.

A profile that works for you

Your name, picture, timezone and preferences you choose to share are filled in automatically at new apps. Change them once, everywhere updates.

Control, finally

See every connected app and agent, what each can access, and revoke any of it in one click. Every agent action is written to your audit log.

Scoped by default

Permissions are granted field by field, not all-or-nothing. An app that needs your email never receives your preferences unless you say so.

Approvals in plain English

Sensitive agent actions pause for your decision: what it wants to do, where, and any limits. Approve or deny. No cryptic permission strings.

Security without friction

Argon2id hashing, login throttling, hashed single-use authorization codes, PKCE and short-lived tokens are built in, not bolted on.

For AI agents

Agents get passes, not passwords.

Today, agents sign in by holding your credentials or a token that never expires. Identvia replaces that with Agent Passes: scoped, expiring, revocable credentials tied to a task, plus a human approval step for anything sensitive. A native MCP server and REST API let assistants like Claude, ChatGPT and your own tools request access the safe way.

  • ✓ Task-scoped, expiring Agent Pass tokens, hashed at rest
  • ✓ Human-in-the-loop approvals with plain-English requests
  • ✓ Daily action limits per agent
  • ✓ MCP tools: get profile, request approval, check decisions
Read the MCP docs
// An agent requests scoped access via MCP { "method": "tools/call", "params": { "name": "identvia.request_approval", "arguments": { "title": "Book flight to Denver", "detail": "UA 1842, $214, Thu 9:05 AM" } } } // → the human approves in Identvia. // → the agent proceeds. Nothing else is unlocked.
For developers

Add sign-in in an afternoon. Not a sprint.

Standard OAuth 2.1 and OpenID Connect with PKCE, so the libraries you already use just work. Prefer hand-rolled? The whole flow is five endpoints and one button snippet. A hosted consent screen means you build zero auth UI.
