+title: Fingerprinting
+description: Learn how to use CrewAI's fingerprinting system to uniquely identify and track components throughout their lifecycle.
+icon: fingerprint
+---
+
+## Overview
+
+Fingerprints in CrewAI provide a way to uniquely identify and track components throughout their lifecycle. Each `Agent`, `Crew`, and `Task` automatically receives a unique fingerprint when created, which cannot be manually overridden.
+
+These fingerprints can be used for:
+- Auditing and tracking component usage
+- Ensuring component identity integrity
+- Attaching metadata to components
+- Creating a traceable chain of operations
+
+## How Fingerprints Work
+
+A fingerprint is an instance of the `Fingerprint` class from the `crewai.security` module. Each fingerprint contains:
+
+- A UUID string: A unique identifier for the component that is automatically generated and cannot be manually set
+- A creation timestamp: When the fingerprint was generated, automatically set and cannot be manually modified
+- Metadata: A dictionary of additional information that can be customized
+
+Fingerprints are automatically generated and assigned when a component is created. Each component exposes its fingerprint through a read-only property.
+
+## Basic Usage
+
+### Accessing Fingerprints
+
+```python
+from crewai import Agent, Crew, Task
+
+# Create components - fingerprints are automatically generated
+agent = Agent(
+    role="Data Scientist",
+    goal="Analyze data",
+    backstory="Expert in data analysis"
+)
+
+crew = Crew(
+    agents=[agent],
+    tasks=[]
+)
+
+task = Task(
+    description="Analyze customer data",
+    expected_output="Insights from data analysis",
+    agent=agent
+)
+
+# Access the fingerprints
+agent_fingerprint = agent.fingerprint
+crew_fingerprint = crew.fingerprint
+task_fingerprint = task.fingerprint
+
+# Print the UUID strings
+print(f"Agent fingerprint: {agent_fingerprint.uuid_str}")
+print(f"Crew fingerprint: {crew_fingerprint.uuid_str}")
+print(f"Task fingerprint: {task_fingerprint.uuid_str}")
+```
+
+### Working with Fingerprint Metadata
+
+You can add metadata to fingerprints for additional context:
+
+```python
+# Add metadata to the agent's fingerprint
+agent.security_config.fingerprint.metadata = {
+    "version": "1.0",
+    "department": "Data Science",
+    "project": "Customer Analysis"
+}
+
+# Access the metadata
+print(f"Agent metadata: {agent.fingerprint.metadata}")
+```
+
+## Fingerprint Persistence
+
+Fingerprints are designed to persist and remain unchanged throughout a component's lifecycle. If you modify a component, the fingerprint remains the same:
+
+```python
+original_fingerprint = agent.fingerprint.uuid_str
+
+# Modify the agent
+agent.goal = "New goal for analysis"
+
+# The fingerprint remains unchanged
+assert agent.fingerprint.uuid_str == original_fingerprint
+```
+
+## Deterministic Fingerprints
+
+While you cannot directly set the UUID and creation timestamp, you can create deterministic fingerprints using the `generate` method with a seed:
+
+```python
+from crewai.security import Fingerprint
+
+# Create a deterministic fingerprint using a seed string
+deterministic_fingerprint = Fingerprint.generate(seed="my-agent-id")
+
+# The same seed always produces the same fingerprint
+same_fingerprint = Fingerprint.generate(seed="my-agent-id")
+assert deterministic_fingerprint.uuid_str == same_fingerprint.uuid_str
+
+# You can also set metadata
+custom_fingerprint = Fingerprint.generate(
+    seed="my-agent-id",
+    metadata={"version": "1.0"}
+)
+```
+
+## Advanced Usage
+
+### Fingerprint Structure
+
+Each fingerprint has the following structure:
+
+```python
+from crewai.security import Fingerprint
+
+fingerprint = agent.fingerprint
+
+# UUID string - the unique identifier (auto-generated)
+uuid_str = fingerprint.uuid_str  # e.g., "123e4567-e89b-12d3-a456-426614174000"
+
+# Creation timestamp (auto-generated)
+created_at = fingerprint.created_at  # A datetime object
+
+# Metadata - for additional information (can be customized)
+metadata = fingerprint.metadata  # A dictionary, defaults to {}
+```
