Why is Google adding an origin trial token meta tag with recaptcha?

[GoogleUser2]

Have noticed this appearing in the document head when inspecting the page. Just wondering what this is and why it's been added. Does anyone know?

Thanks

Hi @GoogleUser2 ,

The origin trial token meta tag you see is added by Google to enable experimental features (like performance or security improvements) in supported browsers. When using reCAPTCHA, Google may include this to test upcoming changes or optimizations on selected sites.

It’s safe and handled by Google — no action is usually needed on your side.

Seems strange that all my websites have this added which suggests either all websites using v3 recaptcha are being targeted or Google just likes me... not sure which 😉
