Other two-factor authentication services

As well as many online banking systems, other websites support two-factor authentication, most of which rely on SMS messages. Services include:

  • Apple
  • Dropbox – a cloud file sharing service
  • Evernote – a cloud-based document and note taking service
  • Microsoft Accounts – used by the Microsoft App Store and its OneDrive cloud storage service
  • PayPal – online payments used by many small web retailers and eBay
  • Steam – online game delivery
  • Twitter

Look out for two-factor authentication on other websites. Set it up to better secure access to your data.
