Why do I get the security risk error?

Hello

I am going to buy an iPhone. I entered the password wrongly when paying using PayBright. I do not know what the online banking password is. However, I can not enter the PayBright page because I have entered the password wrongly several times. I do not know how to solve this problem. In addition, would you please help me with what online password banking is?

Thanks a lot for your assistance in advance.

Bests,
