Isn't this a bug: I register in the iPhone application, enter a password of 5 digits, turn off the keyboard, add 1 digit and everything is erased, only a number remains?

Question

iOS

Register on the app. I enter a 5-digit password in the password field, turn off the keyboard. I decided to add 1 digit to the password, as a result, everything is erased from the field, only 1 this digit remains. I wrote it as a bug, the developer wrote that it's not a bug, "it is specific thing for secureEntryText in textfields".

Answer 1

why not enter all the numbers at once?
