Can it get hacked?
Yes it can be hacked. talking about hacking I think it's applicable to both normal banking system and online banking too. Because there has been several occasions of hacks from bank over the years and most of it is as a result of carelessness of the owner of the account. For example leaving your account information on your phone without locking your phone can be implicating. Sometimes we should completely remove things that will implicate us by deleting bank security detail on phone. rather write it on paper and keep in a safe place, in other not to get hacked when your phone get missing or when we release our phones to people.
If the phone gets missing, can you block the account?
No,
I think you can call there customer support center. Even if they don't have branches does not mean that dey can not attend to there costumers when it comes to security. I think when dealing with online banking we should deal with those that has license or CBN approval just like opay.
if your phone gets missing and you’re using an online bank it will be easily hacked or they can easily take all your money while other banks, if you’re phone or ATM card gets missing you can go to their office and lay a complain and they will close down the account or card.
One important thing you should know is that online banking system should not be a place to put all your funds, it is just like an alternative to banking system incase there is a network issue in normal bank you can run mini transaction on it like pay bills, recharge cards, buy data and some other things but no to put all your funds in. But I don't think hacking online account is possible just as i said earlier. It depends on how secured you are on releasing your privacy.
