What we’re building at WhatsApp Website continues to be motivated by safeguarding the confidentiality of your messages. While end-to-end encryption is the cornerstone for guaranteeing the security of your calls and messages, we continuously add additional layers of privacy on top, such as the recently launched Chat Lock to conceal private conversations behind a password, Disappearing Messages that vanish, screenshot blocking for View Once, and the option to maintain your online anonymity.

We’re pleased to announce the addition of Privacy Checkup and Silence Unknown Callers, which are both currently accessible to users, to this increasing list of enhancements.
