Learn how to add trusted devices to your Klaviyo account.

Before you begin

We recommend that you enable multi-factor authentication (MFA) to help protect your account. If MFA is enabled, follow the MFA verification prompts instead of the email verification steps below.

When you log in with your email address and password without MFA, Klaviyo sends a verification code to your login email address if it doesn't recognize your browser or device. Marking it as trusted saves a cookie in that browser so Klaviyo can recognize it on future logins.

Mark a device as trusted

Only mark devices you control as trusted. If you’re using a shared or public device, leave the checkbox unchecked. You can still enter the code and log in for your current session.

Log in to Klaviyo on the new device.
Enter the 6-digit verification code sent to your login email address.
Verification codes expire after 1 hour.
Select the checkbox labeled Don’t ask me again for this device. Then click Log in.

If you receive a verification email but you did not attempt to log in on a new device, change your password immediately.

FAQs

I don't see a verification email from Klaviyo.If you can't find your verification email in your inbox, double-check all your tabs and folders, including the spam folder.

If you still don’t see the email, add no-reply@klaviyo.com to your contacts or allowlist and check your email filters. On the verification page, open Didn’t receive an email? and select Resend verification email.

What constitutes a new device?Klaviyo uses a browser cookie to recognize a trusted device for your login. Using a different browser, opening a private or incognito window, or clearing your browser’s cookies can require verification again, even on a device you’ve used before.

Do verification codes expire?Yes. Verification codes expire after 1 hour. Resending the same code does not restart the 1-hour period. If your code has expired, open Didn’t receive an email? and select Resend verification email to request a new one.

I don't have access to the email inbox associated with my login credentials.If you don't have access to the email inbox associated with your login credentials, contact your account owner or administrator. They will need to add you as a new user to the account using an email address you can access. If you cannot contact the account owner or administrator, reach out to customer support.
