💡 Quick Tips
- Different PIN for each device — if someone gets one, they don't get everything
- Shield the keypad at ATMs and in public. Shoulder surfers are real.
- Think your PIN got seen? Change it now, not later.
- Use 6 digits if your phone allows it — 100x harder to guess than 4
- Fingerprint + PIN is way better than either alone
