Understand password composition and character diversity. Learn why character set variety matters for password security.
Passwords using only lowercase letters have significantly lower entropy than those mixing uppercase, lowercase, numbers, and symbols. Each additional character type exponentially increases the number of possible character combinations.
A password with all four character types is far more resistant to brute-force attacks than one using only letters, even if they have the same length.
Our analyzer examines each character in your password and categorizes it: uppercase letters, lowercase letters, digits, or symbols. It displays the count and percentage of each type.
This helps you understand your password's composition and identify opportunities to increase diversity for stronger security.
Aim for passwords that include all four character types: uppercase, lowercase, numbers, and symbols. At minimum, mix at least three types. Avoid concentrating characters of the same type consecutively.
Even distribution of character types across the password creates better randomness. Use our password generator to create properly balanced passwords, or check existing passwords with our weak password checker to identify composition issues.

Common questions about password character sets and composition.
Ideally, passwords should include all four character types: uppercase, lowercase, numbers, and symbols. A balanced mix with roughly equal distribution of each type creates maximum entropy.
Position matters for human memorability but less for security. Random distribution of character types throughout the password is ideal, avoiding predictable patterns like numbers only at the end.
A longer password with more variety is stronger than a shorter password with symbols. A 16-character password with only letters can be stronger than an 8-character password with symbols.
