To access your Blink system from a second, or new device, all you need to do is download the Blink app from the appropriate app store and log in with your existing Blink app account email and password.
Each time you log in, the Blink app displays a number entry screen and sends a new PIN number to the mobile phone associated with the account owner. Enter the PIN to access the Blink app and select "Trust this device" if you don't want to enter a PIN for future logins. Click to learn more about how to manage mobile devices with account access.

There is no need to re-create systems and add cameras on the new device because all aspects of your configuration are associated with the account.
Each person that logs in to your account will see the same camera views, they will have account level control over devices and all settings. When someone else logs in with your credentials and deletes a clip, you will no longer see it in the clip list. Only one person at a time; however, has the ability to access Live Views resulting from motion alerts, even though those alerts may appear simultaneously on multiple devices for different people.
To find the account email address on a device that is currently logged in, tap on the Account icon in the bottom right of the screen, and your email is shown at the top of the Account screen that opens.
Email and password information can be changed from this screen.
Account verification is initiated when you attempt to change the email or password.
