Personalization Tool

Yubico offers free personalization tools for Windows, Mac and Linux allowing you to re-initialize the AES key in your YubiKey. The tools can also be used to configure your YubiKey to generate an OATH-HOTP 6 or 8 digit number, or to set a long static password which can be used even offline since it requires no validation server.

If you choose to re-initialize the AES key of your YubiKey, Yubico will not be aware of the new AES key and can't validate the One-Time Passcode (OTP) generated from it. To validate OTPs generated from your newly programmed YubiKey, you need to host your own YubiKey validation server and put the same AES key in the server's database.

WARNING! By re-initializing your YubiKey, either by manually programming a new AES key in the YubiKey or programming the YubiKey for OATH-HOTP or static password, you will lose ALL abilities to use that particular YubiKey against Yubico online severs, including validation server, forum, Wiki, etc. Customers are advised to consider using separate YubiKeys for use in Static Password Mode or for development and testing purposes. If you program your YubiKey with a new AES key protected with a password and forget both the AES key and password, there is no way to restore the YubiKey to a usable state.
