Those without phones can use a security key for DUO.

A security key plugs into the USB port on your computer. When tapped or pressed it sends a signal back to Duo.

• Must have a U2F security key to complete the process.

  • A supported USB security key. WebAuthn/FIDO2 security keys from Yubico or Feitian are good options.

• Go to https://guide.duo.com/security-keys for online instructions and requirements to enroll in Duo 2-factor authentication with a security key.
