Your contact list is fundamental to the experiences you love and enjoy on WhatsApp. With contacts, you know which of your friends and family are on WhatsApp, you can easily message or call them, and it helps give you context on who is in your groups. But losing your phone could mean losing your contact list as well.

作为 WhatsApp 新功能的一部分，您可以在多个链接设备上私密地添加和管理您的联系人，我们宣布推出一种名为身份验证链接存储（IPLS）的新型加密存储系统。IPLS 允许您通过 WhatsApp 保存联系人并自动恢复它们。有了 IPLS，您现在可以直接在 WhatsApp 中创建联系人，并选择将其同步到您的手机或仅安全地保存到 WhatsApp，从而使您能够创建特定于您帐户的联系人。如果您使用链接设备，这还允许您无缝地添加和管理联系人，无论您使用的是哪台设备。

Additionally, if you have multiple accounts on the same phone, such as a work and personal account, you can now customize your contact list for each account. If you lose your phone,...
