Short Answer: You’ll need to link it as if it’s a new card.
👤 Profile (top right)
💳 Link a Card
🏦 Search for your bank
⏩ Follow the prompts by entering in your online banking credentials*
🎉 Voila! Your card is linked
👉 Once your new credentials are linked, you can remove the previous credentials from your Drop account to help avoid confusion in the future!
👉 Some institutions will accept a card number as the username, versus an actual user-generated login (i.e.: Drop4ever)
