Control access to less secure apps

This article is for administrators. For actions users can take, see Less secure apps & your Google Account.

You can block sign-in attempts from some apps or devices that are less secure. Apps that are less secure don't use modern security standards, such as OAuth. Using apps and devices that don’t use modern security standards increases the risk of accounts being compromised. Blocking these apps and devices helps keep your users and data safe.

Examples of apps that don’t support modern security standards include:

  • ​Native mail, contacts, and calendar sync applications on older versions of iPhone, iPad, and OSX
  • ​The mail application on Windows Phone versions earlier than 8.1
  • ​Some computer mail clients such as Microsoft Outlook and Mozilla Thunderbird

Examples of apps that do support modern security standards are Gmail, Instagram, PayPal, Amazon, Facebook, Windows Mail, and Basecamp.
