Why am I getting prompted for Webuath and/or Passkeys
It allows servers to integrate with the strong authenticators now built into devices, like Windows Hello or Apple’s Touch ID. Instead of a password, a private-public keypair (known as a credential) is created for a website. The private key is stored securely on the user’s device; a public key and randomly generated credential ID is sent to the server for storage. The server can then use that public key to prove the user’s identity.

What is Two Factor Authentication (2FA)?
2FA is an additional layer of authentication beyond a username and password. 2FA involves something you know (password) plus something you have with you (like Duo Mobile on your smartphone) to prevent someone from logging in with only your password. With Duo 2FA, you still enter your username and password. The second factor provided by Duo is simply an added layer of security on top of your existing credentials.
