Strong Passwords in 2026: Generate, Test, and Protect Them
Generate secure passwords, test their strength, and check for data breaches with free tools. No sign-up needed. Protect your accounts today.
Your Passwords Are Probably Weaker Than You Think
TL;DR: Weak and reused passwords remain the top cause of account breaches. Free tools let you generate secure passwords, test their strength, and check if they've been leaked.
I got hacked in 2023. Someone logged into my streaming account, then my email, then a shopping site with my credit card. The root cause? Same password on all three accounts.
Why "Good Enough" Passwords Aren't
A strong password needs length (16+ characters), randomness (no real words), and uniqueness (different for every account).
Generate Secure Passwords
The Password Generator creates random passwords with your chosen parameters. Copy it into a password manager.
Test Your Password Strength
The Password Strength Test estimates crack time via brute force.
Check for Leaked Passwords
The Password Leak Checker checks against known breach databases using secure partial hash matching.
Hash Functions for Developers
MD5 Generator (legacy), SHA Generator, Bcrypt Generator (best practice), Hash Generator (multiple algorithms).
Beyond Passwords
SSL Checker for HTTPS validation. More in my SEO audit guide. Email Validator for address verification. Data Anonymizer and PDF Redact for stripping sensitive data.
Key Facts
- Over 80% of data breaches involve weak or reused passwords
- A random 20-character password takes centuries to crack
- Bcrypt is the standard for secure password storage
- MD5 and SHA-1 are cryptographically broken for passwords
- Breach databases contain billions of leaked credentials
- Password length matters more than complexity
- The average person manages 70 to 100 online accounts
- Credential stuffing uses breached passwords across services
FAQ
Is the strength tester safe?
It runs entirely in your browser. Nothing is sent to any server.
How often should I change passwords?
Only when there's a reason: breach notification or leak detection.
Passphrase vs random password?
Both work if truly random. Four or five unrelated words can match a random string.
MD5 vs SHA vs Bcrypt?
MD5/SHA are fast (bad for passwords). Bcrypt is deliberately slow (good for passwords).
Should I use a password manager?
Yes. It's the single biggest security upgrade most people can make.
