What should I do if I…?

Run into a potential security issue? Here are some tips on what to do.

If you get a text message or email claiming to be from Klarna and are unsure, check if it:

  1. Asks you to click on links that take you to fake websites

  2. Asks you to submit sensitive information like personal and payment data or additional ID documents

  3. Has a sense of urgency, like threats of your account being suspended

To report a suspicious email or website, forward it to

and our security team will investigate.

Do not click any links or open attachments from unexpected or unverified sources. Always be cautious of communication asking for personal or financial information, demanding immediate action, or that simply doesn’t look right. If possible, mark the email as phishing in your mailbox and/or delete it. Staying aware and vigilant is the best line of defense.

Immediately contact Klarna and any other relevant institutions involved, including your bank, to tell them. Fast action like freezing your Klarna account can help prevent further problems and keep your account safe. Remember to change your passwords and monitor your financial statements closely for any signs of unauthorized activity.

Immediately contact Klarna to report the lost device or card. You can also freeze your card in the app to prevent unauthorized transactions. Also, if a device like a phone or laptop is lost, change all passwords for accounts accessible on the device and let relevant institutions know about possible unauthorized access—especially if the device is auto-logged-in to any financial or personal accounts.

Immediately contact Klarna to report the suspicious activity and Klarna will investigate. Consider changing any login credentials you think could be compromised and enable additional security tools like two-factor authentication. Regularly monitoring your account for unfamiliar activity can help detect potential fraud early.

Always double check before making any payments, particularly those demanding money urgently and unexpectedly. Log in to your app to check for any outstanding payment. Contact the requester using a different, trusted method to confirm if it’s legitimate.

Before making any purchases online, research the company, check reviews, and confirm valid contact information. Make sure the website is legitimate and secure. Double check the website’s URL is spelled correctly. Also, look for "https://" in the URL which means the data you send to the site is encrypted, providing an extra layer of security. If something feels off, trust your instincts.

Do not open the file. Delete it immediately and run a virus scan. Make sure you have up-to-date antivirus software installed to protect against malicious downloads. Keep monitoring your accounts closely for any unauthorized activity.

Always be cautious when contacted unexpectedly, even if they seem to be legitimate or from a place you trust. If in doubt, end the conversation and independently contact the company directly using a trusted method like the customer service number listed on their official website. It’s always better to double-check before sharing any personal or financial information.
