If you want to link your Blink account to your Amazon or your Alexa account then you need to find the account and privacy menu which is within the settings menu within the Blink app.
Firstly, let me show you how to to link and unlink from your Amazon account
Link/ unlink from Amazon account
Linking your accounts
From the Blink app’s homepage, select the settings menu (bottom right hand side.) Then select the accounts and privacy menu. From here, tap on the link to Amazon account option. On the next page the Blink and Amazon logos appear.
Tap on the blue button at the bottom of the page labelled as Link Account.
A small box appears in the centre of the screen with a spinning blue circle. It says linking.
A screen appears in which to add your Amazon account email address and your Amazon password (for some strange reason this doesn’t show on my video.)
A new screen appears with the Blink and Amazon logos and a green check mark in between them. It says Success Accounts linked. Press the blue button labelled done.
You are taken back to the account and privacy menu within the Blink app.
Unlinking your accounts
Unlinking your account is just as easy.
From the account and privacy page tap on the Amazon account linked text.
The screen shows the Blink and Amazon logos and shows you that your accounts are linked.
At the bottom of the screen in blue writing it shows unlink your account.
Tap on that option and it might warn you that unlinking your accounts will pause your subscription plan.
If you want to go ahead with unlinking then select continue. Enter your Blink password and tap on submit. A small white box appears on screen with a spinning blue circle showing you that your accounts are being unlinked. A page appears asking you if you want to link your Amazon and Blink accounts.
Linking to Alexa
If you want to link your Blink account with your Alexa account, among other things make sure that you have the Alexa app installed on your phone.
In the Blink app, navigate from the homepage to the settings menu and then to the accounts and privacy sub menu.
Towards the bottom of the page you will see the link to Alexa option. Tap on it. A new enable Alexa screen appears. At the bottom select the blue button labelled “open Alexa app”.
In a few seconds your Alexa app should load and at the top you should have a Blink SmartHome notification with a enable to use blue button. Tap on that button.
The login page for Blink appears and so add your email address and password to that and then tap on “continue”.
A verification code with be sent to you. Copy it and add it into the space.
And then select the blue button labelled verify.
The next screen to appear should show that the Blink SmartHome skill has been enabled. You have now linked your Blink account and your Alexa account.
