All Hydrogen issued debit cards come with a unique Personal Identification Number (PIN), set by the cardholder. This even includes virtual and tokenized cards added to a Google, Apple, or Samsung wallet! This extra layer is an important security measure. Hydrogen does not have access to this PIN, it is stored security within the chip of the card.

Please note, as part of our security protocols, we do not allow cardholders or card issuer admins to change the PIN set on any card. If a PIN is forgotten or compromised, please order a replacement card (fees may apply).
