What do you call the act of preventing someone of entering the wrong password many times? Sometimes, you get blocked after 5 attempts, what do programmers call the feature of APIs of preventing the number of tries before locking users out the system?

  • What do you call it? In your language? Have you tried a bilingual dictionary?

  • An attack in form of repeated password entries is called a brute-force attack.You could derive the feature name from it e.g. 'brute-force attack prevention'.

Lockout or account lockout is the name for the practice of blocking further login attempts after a certain number of invalid attempts.

Account lockout is a useful method for slowing down online password-guessing attacks as well as to compensate for weak password policies. These three policies work together to limit the number of consecutive, within a period of time, logon attempts that fail due to a bad password. Ultimate Windows Security

The Account lockout threshold policy setting determines the number of failed sign-in attempts that will cause a user account to be locked. Microsoft


A simple way to call it is account block after X attempts. There is no one word for that as far as I know. So,

Add a feature of account block ...

Yes, it further requires clarification of blocking the account because of unsuccessful attempts... or something like that.
