Open the Revolut app and go to “Settings” → “Security” → “Card PIN.” Select the card you want to reset (physical or virtual). Tap “Reset PIN” and follow the prompts — you’ll need to authenticate with your current PIN, biometrics, or password. Enter your new 4-digit PIN twice to confirm. The new PIN is activated instantly for physical cards at ATMs and payment terminals. For virtual cards, the PIN is used for online verifications or ATM withdrawals via mobile wallet. No need to reissue the card — your existing card works immediately with the new PIN.
