Yes, you can access your WhatsApp backups from multiple devices if you have stored them in an online backup service such as Google Drive or iCloud. When you set up WhatsApp on a new device, you will be prompted to restore your chat history from the backup that is stored in your backup account. Simply select the backup that you want to use and follow the prompts to restore your chat history. However, it’s important to note that you can only restore your chat history on a device that is running the same operating system and WhatsApp account as the device on which the backup was created. For example, you cannot restore an Android backup on an iPhone or restore a backup of one WhatsApp account onto another account. Additionally, if you have end-to-end encryption enabled in your chats, you will not be able to access your chat history from other devices unless you have the encryption key. This is because the encryption key is stored locally on your device and cannot be transferred to other devices or backup services. Overall, while it is possible to access your WhatsApp backups from multiple devices, there are limitations and restrictions to be aware of.
