Recent updates may have expanded access to feature(s) discussed in this FAQ. Visit your product's support page, select the correct hardware version for your device, and check either the Datasheet or the firmware section for the latest improvements added to your product. Please note that product availability varies by region, and certain models may not be available in your region.

Several things may cause this issue. Please refer to the following steps to troubleshoot.

Step1. Ensure you have internet access when you sign up for the TP-Link ID.

Step2. Confirm you have entered a valid e-mail address and password. Please do not use special characters such as &, ~, %, space, etc.

Step3. Troubleshoot if you can’t receive the activation e-mail when signing up for the TP-Link ID.

Step4. If you find the error prompt “The email has been registered”, it means the email is registered as a TP-Link ID. Use this email and its password to log into any TP-Link app (e.g., Tapo, Tether, or Deco). Create a new password if you forget the TP-Link ID password.

Note: All TP-Link apps (e.g., Tapo, Tether, or Deco) share a single TP-Link ID. You only need to register your email once, then you can use the same login for every TP-Link app.
