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.
You can also use this online
password vault tool to securely store your passwords.
We do not store, log any key you enter.
This tool is intended for personal and educational use.
We suggest not to use online tools to protect real production secrets.
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
Our tool encrypts your password directly inside your browser using
AES-256 encryption.
Your actual password is never transmitted to our
server.
We store only the encrypted output, ensuring zero-knowledge
security and complete privacy.
AES-256 is one of the most secure and trusted encryption algorithms
in the world.
It is used by banks, cloud providers, government
agencies, and major enterprises.
With Javascript handling encryption on your device, you get
uncompromised, end-to-end protection.
No.
The saved password is encrypted with AES-256, and
without your personal encryption key,
it cannot be decrypted.
Since your key never travels to the server, the encrypted data
remains protected even in the event of
unauthorized access.
No.
Your password never leaves your device unencrypted.
Only the AES-encrypted version of your password is stored in our
database, making plain-text exposure impossible.
CryptoJS supports PBKDF2 key derivation, but this tool uses AES-256
encryption
instead of hashing.
Encryption allows you — and only you — to decrypt your saved
password using your key.
The server does not store the key, ensuring full
user-side control.
Even in the unlikely event of a data breach, attackers will only see
AES-encrypted strings.
Without your personal encryption key — which only you possess —
the data cannot be decrypted or misused.
Yes — but only on your device in the user profile
section and only if you re-enter your encryption key.
Since we do not store your key, we cannot decrypt your password for
you or recover it if the key is lost.
Yes.
Traditional systems send your password to the server for hashing.
Our approach encrypts your password before it ever touches
the network,
meaning interception, logging, or server compromise cannot expose
your real password.
