What to do if your WeChat is stolen? Here comes the official tutorial. Have you ever encountered a situation where you did nothing and your WeChat account was forced to go offline? Or suddenly received a security alert from the WeChat team showing that your WeChat account is logged in on an unfamiliar device? This could mean that your account password has been compromised. Here are Wechat's recommended steps to protect your account.
Method 1: Self-service account retrieval Step 1: change the password to re-login the account After being forced offline, you can click [Retrieve Password] on the WeChat login page at the first time, fill in the complaint information according to the prompts to complete the complaint, and then reset the password if the complaint is successful. The new password should be a strong one that has never been used before, and make sure that it is not the same as the password used by other websites and apps. Step 2: Delete all suspicious devices Delete all suspicious login devices through the client [Me - Settings - Account and Security - Manage Devices] to avoid account login again in other devices. Step 3: Check whether the binding information has been tampered with.
