Account Lockout and Brute-Force Protection
Learn to defend login endpoints against password guessing by tracking failed attempts and temporarily locking accounts in Spring Security.
The Brute-Force Threat
Attackers automate thousands of login attempts to guess passwords. Without limits, even rate limiting may not stop a slow, distributed guessing campaign against a single account.
Lockout as Defense
Account lockout blocks login for an account after too many failed attempts within a window. This makes online guessing impractical.
