Hello @Karthikeyan Rajendran , Thanks for using Microsoft Q&A Platform.
The Face client SDKs for liveness is a gated feature. We must request access to the liveness feature by filling out the Face Recognition intake form. Once your Azure subscription is granted access, you can download the Face liveness SDK.
Looks like you want to use Face Liveness from any Chrome or Edge browser (not native iOS or Android apps). Currently, Face liveness support for Browser is still in private preview. Raise a support request to get help on the same.
I hope this helps.
Regards,
Vasavi
