Web.whatsapp.com is nice addition on whatsapp it gives you excess over your whatsapp messages on your laptop while your phone charges or when you are working over your laptop .It comeS with high risk if you dont have knowledge of this feature a person can look over your messages without you even knowing . a person also hack your message using this app within10second if he/she has excess to your phone.this feature needs improvement. I personally love this feature but requires update that makes its more risk free other that this feature is awesome. I am giving 2stars for its vunerablity other that its awesome
