## Changing banks

Enrollment in this portal points payments at a specific bank account. When you
switch banks, log back in and update the deposit account for **every payer
listed above**, payers do not share bank changes with each other, even inside
the same portal. Keep the old account open until you see deposits land in the
new one. Full playbook: [Switch banks without missing a payer
deposit](/guides/switch-banks).
