How Strong Should Your Password Be? Password Generator & Strength Checker

Password security is the most basic and most commonly neglected aspect of digital security. Despite decades of warnings, weak and reused passwords remain the leading cause of account compromises. Understanding what makes a password strong — and generating passwords that meet that bar — is a fundamental security practice for individuals and businesses. Password strength is primarily determined by two factors: length and character space. A password drawn from a 95-character set (all printable ASCII) with 12 characters has 95^12 = approximately 5.4 × 10^23 possible combinations. At a rate of 10 billion guesses per second (a realistic GPU cluster rate for offline attacks against weak hashing), cracking this takes millions of years. A 6-character password from the same set? About 6 days. Modern password guidance from NIST (National Institute of Standards and Technology) has shifted away from complexity rules (uppercase + number + symbol requirements) toward length. A 16-character random password, even using only lowercase letters, is astronomically stronger than an 8-character password with all four character types. Length multiplies the search space exponentially. The right password strategy: use a password manager to generate and store unique, long random passwords for every account. Never reuse passwords. Enable multi-factor authentication wherever available — the second factor makes even a compromised password insufficient for account access.
