A user may select or create a PIN at a non-secure input device, such as a web-enabled personal computer. PINs are stored at a financial host in encrypted form, as PIN offsets. The user selected PIN and a corresponding account number are sent in clear text form to the host, which selects a base PIN offset corresponding to the PIN. A host security module within the host converts the base PIN offset to an actual PIN offset using the actual account number. The actual PIN offset (corresponding to the new PIN and the account number) is then stored at the financial host.
