In today’s digital world, your password is the first line of defense against
cyber-attacks.
Weak or predictable passwords are the easiest way for hackers to access personal
accounts, financial data, and sensitive systems.
To help users create safer, stronger, and smarter passwords, we have built a fully
advanced Password Strength Analyzer Tool powered
by strong cryptographic techniques, rule-based validation, brute-force estimation,
and intelligent password suggestions.
Any secret key value that you enter, or we generate
is not stored on this site, this tool is provided via an HTTPS URL to ensure that
any
secret keys cannot be stolen.

We are thankful for your never ending support.
This tool is far beyond a basic “weak/strong” checker — it provides a detailed
breakdown of password vulnerabilities, real-time scoring,
crack time estimation, dictionary attack detection, l33t pattern detection, and
human-readable secure password alternatives.
Why Use Our Password Strength Analyzer
Our tool is designed for:
- Everyday internet users
- Developers
- Security professionals
- Students learning cybersecurity
- Companies enforcing strong password policies
It provides an in-depth analysis that most password checkers do not offer.
Key Features of the Password Strength Analyzer
Real-Time Password Scoring (0–100)
The tool evaluates your password based on:
- Character diversity
- Length
- Entropy
- Presence of uppercase, lowercase, digits & symbols
- Penalties for weak patterns
Score ranges:
- 0–40 → Weak
- 41–69 → Moderate
- 70–100 → Strong
Brute-Force Crack Time Estimation
Know exactly how long it would take an attacker to crack your password using
brute-force methods.
We show results like:
- “2 minutes”
- “6 hours”
- “12 years”
- “350 centuries”
This gives users a practical understanding of their password’s real-world
strength.
Dictionary Attack Detection
The tool checks your input against a curated list of:
- Common passwords (10k list)
- Frequently used predictable patterns
- Keyboard sequences like qwerty, 1234, asdf
If your password even resembles a dictionary word, you get instant warnings.
Repeated Characters & Pattern Detection
Detects:
- aaa
- 1111
- abcd
- qwerty
- 123456
These are extremely risky patterns that hackers love.
L33T Substitution Detection
Hackers can easily reverse l33t substitutions like:
- P@ssw0rd → password
- Adm1n → admin
- h4ck3r → hacker
Our tool analyzes the underlying word even after substitutions.
Human-Readable Strong Password Suggestions
Unlike random password generators, we produce easy-to-remember but hard-to-crack
passphrases:
Examples:
- Crystal-Ocean-42!
- River-Sunset-93@
- Shadow-Fusion-81#
You get multiple suggestion types:
- Stronger variant
- Pattern breaker
- Dictionary-safe version
- L33t-safe version
- Human readable strong passphrase

Frequently Asked Questions
Quick answers about how the Password Strength
Analyzer works, privacy, and best practices.
No. We do not store or log the passwords
you enter. Analyses are performed in real-time and results
are returned to your browser. If your setup sends the
password to your own backend (for advanced checks), ensure
your server uses HTTPS and does not persist or log the
password. Treat the analyzer as a one-time check and avoid
reusing test passwords on untrusted machines.
Yes — generated passwords and passphrases are designed to be
strong and hard to guess. The human-readable suggestions use
multiple words, numbers, and symbols to increase entropy
while remaining memorable. We don’t store the generated
passwords; copying happens in your browser. If you use the
generator server-side, ensure the server does not persist
the generated values.
Aim for at least 12 characters for most
accounts and 16+ characters for high-value
accounts (banking, primary email). Passphrases made of
several unrelated words (e.g., River-Orange-93!)
are easy to remember and provide high entropy compared to
short complex strings.
Attackers run dictionary and wordlist attacks that try
millions or billions of common words and phrases per second.
If your password is a common word, common phrase, or a small
modification of one (e.g., p@ssw0rd), it can be
cracked quickly. Use uncommon word combinations, add
separators, numbers, and symbols, or use a password manager
to generate random high-entropy passwords.
Entropy measures how unpredictable a
password is (expressed in bits). Higher entropy means more
possible combinations and more time required to brute-force
the password. Entropy increases with password length and
character diversity (mix of upper/lowercase, digits,
symbols). Our analyzer estimates entropy to give a practical
sense of password strength.
Review the suggested passwords and choose one that fits your
needs. For everyday use, pick the human-readable passphrase
(e.g., Crystal-Ocean-42!) and store it in a
password manager. If you must memorize a password, use the
"stronger variant" that preserves some familiarity but
removes weaknesses. Avoid reusing passwords across multiple
sites.
Yes — you can adapt the tool to accept multiple inputs or a
"compare" mode. Comparing two passwords side-by-side helps
evaluate which one is stronger and why. We recommend running
each candidate through the analyzer and reviewing entropy,
crack time, and detected weaknesses.
