One Identity offers you the option to log in, simply and securely, to One Identity Manager web applications with help of (physical) security keys. If your system is configured for it and you own security keys like this, you must use the security key when you enter your password to log in to a web application (for example, to the Web Portal). These security keys support the W3C standard WebAuthn.
IMPORTANT: The WebAuthn standard is NOT support in Internet Explorer. Therefore, use another browser if you want to log in to One Identity Manager web application using security keys.
