# Password Safe and YubiKey

YubiKey is an innovative hardware authentication device developed and sold by Yubico. To the user, it looks like a small, thin, disk-on-key with a button on top. To Password Safe, it functions as an authentication token, providing strong physical security to the password database. |

## Getting YubiKey

Obviously, you need a YubiKey device to start. YubiKeys can be purchased online from here. Note that Password Safe requires YubiKeys with firmware version 2.2 and above.

## Configuring your YubiKey

Your YubiKey needs to be configured properly in order to work with Password Safe. This is done via the Manage->Yubikey... dialog box as described in the Manage Menu Section.
If you already have a YubiKey, note that Password Safe uses slot #2 for authentication, leaving slot #1 for other applications.

## Using YubiKey

Once your YubiKey is configured, you can use it, along with you master passphrase, to protect your Password Safe database, as described in Creating a New Safe.
