Quick security recommendations for your devices

We are often asked where can one start, what are minimum steps should one consider taking in an effort to better protect their devices. Below we are sharing what we are recommending as the first, often most effective and most important items.

General

  1. Use unique and strong passwords for each account, using a password manager to safely store them.
  2. Use Two-Factor Authentication (2FA) on supported accounts. First consider using hardware tockens (see below), then using time-based one-time password (TOTP) apps/programs. Avoid using SMS for 2FA if you can.
  3. Avoid using biometrics (face ID, fingerprint scan) as an authentication method.
  4. Delete old files, documents, pictures, screenshots and chat history that you do not need on your device. Securely backup as necessary before removal.
  5. If you can, avoid installing social media apps, you can use the website with your browser.
  6. Restart your device frequently, this ensures updates are applied properly and for cases of non persisten malware, that the risk can be reduced.
