Circle Security

For organizations looking to reduce password-based attacks, Circle Security helps employees sign in without usernames or passwords. At a supported login screen, users scan a QR code with the Circle app to answer a one-time authentication challenge from their phone. The flow is designed to prevent attackers from stealing or phishing reusable login credentials. Organizations can connect Circle to existing identity systems, including Okta, Microsoft Entra and Google Workspace, using standards such as SAML and OIDC. Circle also supports passwordless access across web browsers, Windows login, remote desktop and mobile. It is intended for businesses and other organizations deploying Circle for secure access; users will need their organization to support the service.
