Analyze your digital security score
This password strength checker provides a live analysis of your login credentials as you type them. The tool calculates a score from 0 to 100 based on specific character types and patterns. It rewards length with 4 points per character added to the string. Symbols provide a higher bonus of 6 points each for extra security.
You lose points for repeating characters or sequential letters in your choice. The password complexity checker identifies common patterns like consecutive numbers or symbols. A 16 character lowercase password is often stronger than an 8 character complex one. This happens because total combinations scale exponentially as Alphabet Size ^ Length.
The password strength test also estimates cracking times for different hardware types. A standard high end desktop takes 8 years to crack a weak password at 10 billion guesses per second. A botnet network can guess 100 trillion times every second. Government supercomputers might crack some codes in just 4 minutes. The tool uses variables like length (len) and character count (n) to determine your final score.
