Cyber security checklist


Your username and password is what keeps your information safe. Follow our tips to protect your details from fraud.

Password security advice

  • Keep your passwords secret, don’t share them with anyone else
  • If you suspect that someone else knows your password, change it immediately
  • When you change or create new passwords, make sure they’re different from previous ones
  • Don’t use the same password for different services and sites
  • Create passwords that are fairly complex, but easy to remember
  • Use a password manager to keep control over your login details for different sites and services

Remember: no one should ever ask for your password. If someone does, it might be part of a fraud attempt.


Your email account contains a lot of private information, as well as alerts and notifications from Zettle.

Email security advice

  • Keep your email account secure and enable multi-factor authentication (MFA)
    - For example, use Google or Microsoft Authenticator
  • Never share sensitive information in emails
    - Treat emails like postcards, as if anyone can read the information you send and receive
  • Links and attachments sent via email might be phishing attempts or malicious code
    - Think twice before clicking links in emails

Computers and devices

Your smartphone, tablet or computer is your way to access your Zettle account – but they can also be the way in for attackers.

Computer security advice

  • Update all software installed on your device
    - For example: Chrome and Acrobat Reader
  • Make sure that the operating system on your device is updated automatically
    - For example: Enable Microsoft Update or iOS/Android Auto Update
  • If you use a computer, install an anti-malware program from a trusted supplier
  • Make sure that you have a firewall enabled
  • Secure your device with a password
  • Lock your device when you leave it unattended
  • Only log in to your Zettle account from trusted devices and networks


We’re connected to the internet frequently every day, so it’s important to know how to protect ourselves from malicious content and services.

Internet security advice

  • Be vigilant and sceptical, avoid clicking links you get from untrusted sources
  • Only submit your personal information to sites that you trust
  • Ensure that the site you access is valid by preferring sites using ‘HTTPS’ at the beginning of the URL
  • Log out when you leave a site providing services with sensitive information (such as Zettle)
  • Think carefully about software you download and install from the internet - there are many that exist only to steal your information
