GitHub Personal Access Tokens (PATs) are a secure way to interact with GitHub, especially for API calls and command-line operations. Two types of PATs exist: fine-grained and classic tokens. Fine-grained tokens grant access only to necessary resources, while classic tokens provide broader access.

To use PATs securely:

1. Create tokens with the minimum privilege required.
2. Use fine-grained tokens whenever possible.
3. Limit access to only what's needed.
4. Cache credentials temporarily to reduce re-entry.
5. Regularly clean up unused tokens and implement stricter token management rules.

By following these best practices, developers can create more secure workflows while minimizing risks associated with mismanaged tokens.
