    Core capabilities

    Device trust verification
    Establishes device trust as part of the login flow before allowing secure access to company networks and applications.
    Duo Push authentication
    Sends an access request to a user’s smartphone for approval as a possession-based second factor during login.
    Multi-factor authentication methods
    Supports additional verification methods beyond a password, including biometrics, TOTP, callback verification, tokens, and FIDO2 security keys.
    Phishing-resistant security keys
    Works with FIDO2 security keys as a phishing-resistant second- or multi-factor authentication method because the key remains in the user’s possession.
