Authentication by third-party cookies within Twinfinity has been deprecated. If you build apps, extensions, or integrations against Twinfinity, you should transition to token-based authentication. This change follows evolving web standards and best practices for stronger security and better user privacy.

## Background

In recent years, all major web browsers have been moving away from supporting third-party cookies, primarily because of concerns around user privacy and cross-site tracking. As a result, relying on third-party cookies for authentication or other critical functionality is no longer a sustainable or secure approach.

## What this means for you

1. **Immediate action needed**: If you currently rely on third-party cookies for authentication in your own apps, extensions, or integrations with Twinfinity, you should transition as soon as possible.
2. **Assistance available**: For help configuring token-based authentication, reach out through the [Twinfinity Help Centre](https://help.twinfinity.com). Our team can guide you through the process to ensure a smooth transition.

For the current OAuth client-credentials flow used by server-to-server integrations, see [Syncing data to external systems with events](https://twinfinity.atlassian.net/wiki/spaces/HCFD/pages/1643085835).

## Benefits of token-based authentication

- **Enhanced security**: Tokens provide a more secure and streamlined authentication process.
- **Reduced dependence**: Unlike cookies, tokens don't rely on browser support, making them a more future-proof solution.
- **Improved user experience**: Token-based authentication often results in faster loading times and a smoother experience.

## Conclusion

The deprecation of third-party cookie authentication follows industry trends focused on improved security and user privacy. Take proactive measures and transition to token-based authentication to avoid disruptions when accessing Twinfinity. If you have any concerns or need more information, the Help Centre is here to help.
