 # Transfer Subkeys
 
 **Important** Verify a backup of Subkeys was made before proceeding. Transferring keys to YubiKey is a one-way operation: `keytocard` converts the local, on-disk key into a stub, which means the on-disk copy is no longer usable to transfer to subsequent YubiKeys.

+The currently selected key(s) are indicated with an `*` symbol.  When transferring keys, only one subkey must be selected at a time.
 
 The Certify key passphrase and Admin PIN are required to transfer keys.
