    Add your credential to the YubiKey with touch or NFC-enabled tap. Hardware-backed strong two-factor authentication raises the bar for security while delivering the convenience of an authenticator app.

    Self-service reduces IT costs

    Users switch phones often. With other authenticator apps, when a user has a new phone or OS upgrade, IT often needs to help reset the enrollment flow and support calls rack up costs.

    The Yubico Authenticator app allows for user self-service to enroll multiple secrets across various services, making this a secure and efficient solution at scale.
