*typo: ignore the first line*

So just the authenticator for 2FA or does it actually store passwords as well?

it is a mfa hardware authenticator key. it does not store passwords, except for when using the yubikey in secure static password mode where it is recommended the user store only half of a password i.e. the user types the first half, then uses the yubikey to complete the other half.
