<p>Global variables let you store and reuse generic input values and credentials across your projects.
|
||
You can use a global variable in any text input field that displays the 🌐 icon.</p>
|
||
<p>Langflow stores global variables in its internal database, and encrypts the values using a secret key.</p>

<p>Optional: Select a <strong>Type</strong> for your global variable. The available types are <strong>Generic</strong> (default) and <strong>Credential</strong>.</p>

|
||
<p>Even though Langflow stores global variables in its internal database, and encrypts the values using a secret key, you should consider taking extra precautions to ensure the database and secret key are protected.</p>
|
||
<h3 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="use-a-custom-secret-key">Use a custom secret key<a class="hash-link" aria-label="Direct link to Use a custom secret key" title="Direct link to Use a custom secret key" href="/settings-global-variables#use-a-custom-secret-key"></a></h3>
|
||
<p>By default, Langflow generates a random secret key.
|
||
However, you should provide your own secret key, as it's more secure to use a key that is already known to you.</p>
|
||
<p>Use the <code>LANGFLOW_SECRET_KEY</code> environment variable to provide a custom value for the secret key when you start Langflow.</p>
|
||
<h3 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="protect-the-secret-key">Protect the secret key<a class="hash-link" aria-label="Direct link to Protect the secret key" title="Direct link to Protect the secret key" href="/settings-global-variables#protect-the-secret-key"></a></h3>
|
||
<p>Make sure to store the secret key in a secure location.</p>
|
||
<p>By default, Langflow stores the secret key in its configuration directory.
|
||
The location of the configuration directory depends on your operating system:</p>
|
||
<ul>
|
||
<li>macOS: <code>~/Library/Caches/langflow/secret_key</code></li>
|
||
<li>Linux: <code>~/.cache/langflow/secret_key</code></li>
|
||
<li>Windows: <code>%USERPROFILE%\AppData\Local\langflow\secret_key</code></li>
|
||
</ul>
|
||
<p>To change the location of the the configuration directory, and thus the location of the secret key, set the <code>LANGFLOW_CONFIG_DIR</code> environment variable to your preferred storage directory.</p>
|
||
<h3 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="protect-the-database">Protect the database<a class="hash-link" aria-label="Direct link to Protect the database" title="Direct link to Protect the database" href="/settings-global-variables#protect-the-database"></a></h3>
|
||
<p>Make sure to store Langflow's internal database file in a secure location, and take regular backups to prevent accidental data loss.</p>
|
||
<p>By default, Langflow stores the database file in its installation directory.
|
||
The location of the file depends on your operating system and installation method:</p>
|
||
<ul>
|
||
<li>macOS: <code>PYTHON_LOCATION/site-packages/langflow/langflow.db</code></li>
|
||
<li>Linux: <code>PYTHON_LOCATION/site-packages/langflow/langflow.db</code></li>
|
||
<li>Windows: <code>PYTHON_LOCATION\Lib\site-packages\langflow\langflow.db</code></li>
|
||
</ul>
|
||
<p>To change the location of the database file, follow these steps:</p>
|
||
<ol>
|
||
<li>Set the <code>LANGFLOW_SAVE_DB_IN_CONFIG_DIR</code> environment variable to <code>true</code>.</li>
|
||
<li>Set the <code>LANGFLOW_CONFIG_DIR</code> environment variable to your preferred storage directory.</li>
