Frequently Asked Questions

Kotak Mobile Banking app login PIN is different from net banking password — right? Yes — Kotak app uses a separate MPIN (4–6 digit PIN). Net banking uses a different password. Reset one doesn't affect the other.

My Kotak net banking was fine yesterday, now shows "invalid customer ID" — why? Could be a caching/cookie issue. Try incognito browser, clear cache, try on mobile browser. If still failing: use "Forgot Password" flow even if you know the password — it verifies your Customer ID.

Can I use Kotak net banking on mobile without the app? Yes — netbanking.kotak.com works on mobile browser. Use incognito mode for better performance.
