Only one email address at a time can be used with a Blink account; however, if you need to modify the current email of your account, you can do this in the Blink app.
From the Home screen, tap on the Settings icon and then select Account and Privacy.
Your current email address is displayed under Account Settings at the top of this screen. Tap the email, enter your account password in the security popup and tap Submit.
If you enter the correct password, you are shown a Change Email screen. Enter your new email address and tap Change Email. A verification email will be sent to the new address, so be sure you have access.
** Please note that the new e-mail address must not be an e-mail address that has already been registered by the app at Blink. Changing this email address will not affect your blinkforhome.com email address. These are separate accounts.
Once you receive a verification email you must enter the code and tap Verify to continue.
You will then be taken to the main Welcome screen where you can login with your changed email address.
