# Connect OpenStreetMap with No Authentication (public APIs only) – StackOne Hub

> Link a OpenStreetMap account in the StackOne Hub using No Authentication (public APIs only). End-user guide to authorize the integration and start using OpenStreetMap actions.

<section data-guide-section data-guide-scopes="">
  <h2>Connect without credentials</h2>

  <p>The <strong>No Authentication (public APIs only)</strong> method needs no account, API key, or OAuth application. It connects to OpenStreetMap's public read and query APIs only, so there is nothing to configure on OpenStreetMap's side.</p>

  <Steps>
    <Step title="Select the No Authentication method">
      <div data-guide-step data-guide-scopes="" data-guide-display-scopes-list="">
        <p>In StackOne Hub, choose the <strong>No Authentication (public APIs only)</strong> method and connect. Leave all credential fields empty — none are required.</p>
      </div>
    </Step>

    <Step title="Review what this connection can access">
      <div data-guide-step data-guide-scopes="" data-guide-display-scopes-list="">
        <p>This connection can call only OpenStreetMap's public, credential-free APIs:</p>

        <ul>
          <li><a href="https://nominatim.openstreetmap.org" target="_blank" rel="noopener noreferrer">Nominatim geocoding</a> — search, reverse-geocode, lookup, details, and status.</li>
          <li><a href="https://overpass-api.de" target="_blank" rel="noopener noreferrer">Overpass API</a> — Overpass QL feature queries.</li>
          <li>Public OpenStreetMap read endpoints — map data, nodes, ways, relations, changesets, notes, user profiles, and API capabilities.</li>
          <li>Any action that edits the map or reads a user's private data (element/changeset/note writes, preferences, GPS traces, messages) requires the <strong>OAuth 2.0</strong> method instead and will fail on this connection.</li>
        </ul>

  <h2>Linking the Account from the Hub</h2>

  <Steps>
    <Step title="Navigate to the Hub">
      Use one of the three <a href="/connect/managing-connectors/linking-accounts">Linking Account Methods</a> to access the Hub.
    </Step>

    <Step title="Connect">
      <ul>
        <li>Click <strong>Connect</strong></li>
        <li>If applicable, the provider will redirect you to a sign-in or authorization page. Complete the provider's authorization flow.</li>
        <li>Once authorization is successful, you will see a confirmation popup</li>
      </ul>
    </Step>
  </Steps>

  <p>If the account linking is successful, you will see the newly linked account in your <a href="/gateway/concepts/linked-accounts">Accounts</a> page.</p>
