Trusted Devices is an extra layer of security for your Blizzaccount. As a preventive measure to ensure your account's security, you need to authorize a new device on which you sign in to your account for the very first time.


Note: You will recieve an Email from TeamViewer as Blizz is part of the TeamViewer family and the Blizz account run through the same high level of security as the TeamViewer servers.


How it works:

1. After signing in to the Blizz client or the Blizz Management Console with your account credentials on a new device for the first time, a pop-up appears.

2. A sign-in confirmation email is sent to the email address of your Blizz account.

3. Click the Add to trusted devices link within the sign-in confirmation email, to authorize the device. The new device is now a trusted device.

4. Here, you can complete the authorization process by choosing the kind of trust scope you would like to grant followed by clicking on the blue button Trust. The location may not always be 100% exact, as it is given by your Internet Service Provider.

5. Please choose from the dropdown menu whether you would like to trust this specific device or the IP address permanently or whether you would like to trust this device only once

Note: The link in this email is only valid for 30 minutes. If the link expires, you will need to sign into your account once more on the new device, so that a new authorization email can be generated.


5. A message is displayed informing you that the new device is now a trusted device.




What each Trust Scope means:

Trust device

You are setting the trust for the specific device.

Trust IP address

You can decide whether you would like to trust a single device only or if you would like to trust the IP address. That means your account's trust is extended to all other devices in the same local network. You can now login with all devices/instances that log in from the trusted IP address.
When the IP address changes, you will get the trusted device mails only for new devices, that haven't signed in before the IP address has changed.

Trust only once

This trust scope can be used, when you only want to login on the device once (on a device from your customer, in an Internet cafe,... ). It is only valid for one login on the device. 

The trust will be deleted after you logged in from the trusted device. When you try to re-loginyou will get the trusted device message again.


Once you complete the authorization process, you are able to sign in on the new device with your Blizz account credentials.


Two Factor Authentication (Alternative to Trusted Devices)

As an alternative to the Trusted Devices authorization process, you can enable two-factor authentication on your account instead. If you are using two-factor authentication, then the Trusted Devices authorization email won’t be required anymore when you sign into your account on a new device.

You can activate the 2 Factor Authentication once you login with your Blizz account. Click on your name on the upper left side, and then click on the pencil on the upper right side to edit your account. Under Two Factor Authentication, choose Activate. You will then be guided through the process.
