3. Enable Easy Access
The newest secure way to access a device with TeamViewer is through Easy Access. When Easy Access is enabled on a device and that device is assigned to your TeamViewer account, no random or personal password is required. You simply need to be logged in to your account. The only way someone else could access that device is with the device ID and password, so if you’ve eliminated passwords, you have limited access to only your device (and your group, if you have assigned the device to a group).
This approach is more secure than those involving passwords due to one powerful feature: two-factor authentication. Securing your TeamViewer account with two-factor authentication significantly reduces the chances of someone other than you is accessing your device(s). For more on how to enable two-factor authentication at the account level, check out our TeamViewer Community article.
Setting up Easy Access is… well, easy.
If someone already assigned the device to your TeamViewer account: Click Extras –> Options –> Security –> under Unattended access, activate the checkbox Grant easy access –> click OK.
If the device is not yet assigned to your TeamViewer account: Click Extras –> Options –> Security –> click the Configure button –> The Assign to account dialog box will open –> Click the Assign button –> Under Personal Password (for unattended access), activate the Grant easy access checkbox –> click OK.
