Summary
This is a new API for propagating a notion of user authenticity across sites, without using cross-site persistent identifiers like third party cookies. Trust Token is built on Privacy Pass for anonymous tokens that can't be tracked between issuance and redemption.
An Origin Trial for Trust Token started in M84 and is scheduled to end in M87. Due to complexities in the initial deployment and changes to the API, we are looking to extend the origin trial to get additional feedback and data. We would like to extend the Origin Trial to M91.

Goals for experimentation
For the continuation of the origin trial, we still hope to see that token-derived signals can be used for fraud detection without 3P-cookie based schemes. Additionally, we plan on releasing more thorough documentation and a higher-level interface to some of the cryptographic logic; extending the origin trial will give other parties time to participate in this more user-friendly environment.
Experimental timeline
We'd like to extend the Origin Trial to run to M91.
Any risks when the experiment finishes?
As this feature is only available via Origin Trials and doesn't affect any existing state, we don't believe there will be any risks once the experiment concludes.
Reason this experiment is being extended
https://groups.google.com/a/chromium.org/d/msg/blink-dev/UIvia1WwIhk/DuXLKdF7AgAJ
To gather additional feedback and data on the API and new API changes and try to get more participation before moving to shipping the feature.
Ongoing technical constraints
None.
Will this feature be supported on all five Blink platforms supported by Origin Trials (Windows, Mac, Linux, Chrome OS, and Android)?
Yes.
