How to keep your mobile wallet secure
The security of your bKash, Nagad or Rocket account is in your own hands. A few simple habits can significantly reduce the risk of fraud.
Never share your PIN
No ck 4440 representative or customer care agent will ever ask for your mobile banking PIN. If anyone does, it is a scam.
Keep your OTP private
Never share the OTP code received during a transaction with anyone — not by phone, message or chat. This code is for you only.
Use official apps only
Use the official bKash, Nagad or Rocket app. Avoid logging in through third-party apps.
Use a trusted network
It is best to avoid transacting over public Wi-Fi. Mobile data or your home network is more secure.
