Check your password composition in seconds and see which uppercase, lowercase, number, and symbol sets are present.
Understand password composition and see why diversity matters for stronger security.
A password made from only lowercase letters is far weaker than one that mixes uppercase letters, lowercase letters, numbers, and symbols. Each extra character type expands the number of possible combinations and makes brute force attacks much harder.
A password with all four character sets is generally more resistant to guessing than one using just letters, even when the length is the same.
The analyzer checks each character and groups it into uppercase, lowercase, numbers, or symbols. It then shows counts and percentages so you can quickly see what is missing.
This makes it easier to improve an existing password or build a new one with better balance and variety.
Try to include all four character sets whenever possible. If that is not practical, include at least three and keep the password long enough to stay strong. Avoid repeating the same type of character over and over.
Use our password generator to create balanced passwords, or check existing ones with our weak password checker to spot composition problems.

Common questions about password character sets and composition.
Ideally, your password should include uppercase letters, lowercase letters, numbers, and symbols. A balanced mix gives you more entropy and stronger protection.
It matters less for security than randomness does. A varied password spread across the whole string is usually better than one that uses the same type of character in a predictable pattern.
Not always on its own. A longer password with more variety is usually stronger than a shorter password with symbols only.
