Profesyonel Password Strength Checker

Özellikler

Rule-based strength scoring: length, character class diversity, repetition / sequence detection
Common-password match check (top ~40 most-cracked passwords + simple suffix variants)
Estimated crack-time at 10 billion guesses/second (GPU-attack assumption against unsalted hash)
Inline criteria checklist showing which rules are met
Runs entirely in your browser; nothing is sent to a server

Length beats complexity. A 20-character passphrase of common words is stronger than an 8-character "P@ssw0rd!" alternative.
Use a password manager — generated random passwords are stronger than anything you'll remember, and you only have to remember the master.
Common-password detection catches the top ~40 most-cracked entries. For production-grade strength estimation, use zxcvbn or check against the Have I Been Pwned API.
Crack-time estimates assume an unsalted password hash and a GPU farm. Real systems use slow hashing (bcrypt, argon2) which makes attacks much slower.
Never reuse passwords across services — credential-stuffing attacks rely on it.
