Hello!

I’m sorry but I don’t understand what you wanted to say. Please reformulate.

Actually his different to u2f now android devices start be have same features like security keys

I do not use the biometric security features on any device, for no reason in particular.
I could see a benefit over SMS using device biometrics as long as it is all in the device.
