Brute-force
In short and in plain language
A brute-force attack tries a huge number of passwords until the right one works.
A program does this by itself. It often targets the login pages of shops and admin areas.
Limits on login tries can lower the risk. So can an extra check when people sign in.
Definition
A brute-force attack automatically tries a very large number of passwords or combinations until one works. Targets are often the login pages of shops and administration areas. Limits on login attempts and a second protection step at sign-in can reduce the risk.
