Securing your Blink Account with Multi-Factor Authentication

If your phone number has changed, or you can't access the phone number associated with your Blink account, contact customer support for assistance. Please note, you must be with your Blink devices in order for customer support to assist you.

What is Multi-Factor Authentication

At Blink, we take the security of your account seriously. That's why we've implemented a two-step verification process, also known as two-factor authentication or multi-factor authentication (MFA). The extra layer of authentication helps prevent unauthorized users from gaining access to your Blink account, even if they have your username and password.

When you attempt to log in to your Blink account you’ll receive a one-time, six-digit code to verify it's you. This is sent to your mobile device as a text message (SMS). You can choose to receive this one-time passcode via the email address you have listed on your Blink account or on your phone as a text message (SMS).

Verification codes and emails are sent directly to the main account holder, ensuring that only the authorized user has access to the account. If you want to share your account with other trusted individuals, they will need to obtain the verification codes from the main account holder.

Multi-Factor Authentication FAQ

Why does Blink need my phone number?

At Blink, we value your security and privacy, which is why we take great care in safeguarding your account and devices. To ensure that important changes are authorized by the account owner, we ask for your phone number. Rest assured that your phone number remains confidential and is never sold or used for marketing purposes.

We ask for your phone number to provide a secure and convenient means of authorizing the following actions on your Blink account:

  • Login to your Blink account
  • Reset, forgot, or change your password
  • Log in to a new device
  • Change your phone number
  • Change your email address

To make authorization easier, Blink uses SMS text messages to send a one-time PIN to the phone number registered on your account.


What is a verification code?

A verification code is used to authenticate your identity. As part of our verification policy, Blink sends an SMS text to your mobile device containing a six-digit verification code. Once you enter or share the six-digit number code, you can complete your account setup, changes in the Blink app, or customer service can continue your support call. 

Verification codes can also be sent via email or can be read to you by an automated voice call.

Note: Charges may apply for receiving SMS text messages. We recommend checking with your phone service provider for more information.


What steps can I take if I'm not receiving a verification code or PIN?

If you are not receiving your verification code (also known as a PIN), please follow these steps:

  • Check if your mobile device carrier is flagging your code notification as spam.
  • If you are receiving your PIN via email, kindly check your email's spam, trash, and promotions folders. If you still cannot find it, try accessing your email on a different mobile device or computer.

If none of these steps help to resolve your issue, please contact customer service so that we can assist you with troubleshooting.


What if I don't want to receive an SMS text message?

If you prefer not to receive your verification code by SMS text, the verification code can be read to you by an automated voice call.

  1. Tap Settings at the bottom of your home screen.
  2. Select Account and Privacy > Account Management.
  3. On the Account and Privacy screen tap Phone Number.

    Note: If you have forgotten your password, you must reset your password before you can update your phone settings. If you no longer have access to the account phone number associated with your Blink account, contact customer support for assistance.
  5. On the Change Phone Number screen, tap Receive code by and select Voice call.
    Both mobile and landline numbers can be used with the Voice call option. Contact customer support if you have any concerns.
