Frequently Asked Questions
A secure password should be:
- Long - At least 12 characters, preferably 16 or more
- Complex - Contains uppercase, lowercase, numbers, and special characters
- Unique - Not used for any other account
- Random - Not based on dictionary words or personal information
Our password generator creates passwords that meet all these criteria, with customizable options to suit your needs.
Our strength meter evaluates passwords based on:
- Length - Longer passwords are stronger
- Character variety - Using multiple character types increases strength
- Randomness - Avoids patterns or predictable sequences
- Entropy - Measures the actual unpredictability in bits
The meter shows three levels: Weak (red), Medium (yellow), and Strong (green). For maximum security, aim for passwords that register as Strong.
Password entropy measures the unpredictability of a password in bits. Higher entropy means the password is harder to guess or crack through brute force attacks.
Our calculator estimates entropy based on:
- The size of the character set used
- The length of the password
- Whether the password appears truly random
As a general guideline:
- 28-35 bits: Weak (vulnerable to brute force)
- 36-59 bits: Medium (reasonable for low-value accounts)
- 60+ bits: Strong (recommended for important accounts)
No. All password generation happens in your browser. We never send your passwords to our servers or store them anywhere.
You can optionally enable "Password History" to temporarily store passwords in your browser's local storage (until you close the browser), but this is completely optional and disabled by default.
For maximum security, we recommend:
- Generating passwords in a private/incognito browser window
- Copying passwords directly to your password manager
- Avoiding saving passwords in browsers or unencrypted files
Passwords are typically shorter strings of random characters that are hard to remember but provide good security when long enough.
Passphrases are longer combinations of random words that are easier to remember but can be just as secure (or more secure) than traditional passwords.
Key differences:
| Passwords | Passphrases | |
|---|---|---|
| Length | Typically 12-20 characters | Typically 20-40 characters |
| Memorability | Hard to remember | Easier to remember |
| Security | High when sufficiently long and complex | High due to length, even with simpler characters |
| Typing | Harder to type accurately | Easier to type accurately |
| Best Use | Password managers, important accounts | Accounts you need to remember, master passwords |
Our tool generates both types so you can choose what works best for each situation.
We strongly recommend using a dedicated password manager. Here's why:
- Encrypted storage - Keeps passwords secure even if your device is compromised
- Auto-fill functionality - Prevents phishing by filling passwords only on correct sites
- Cross-device sync - Access passwords on all your devices securely
- Password generation - Most managers include built-in generators
- Security alerts - Notify you of compromised passwords
Popular options include:
- Bitwarden (free and open source)
- 1Password
- LastPass
- Dashlane
- Keeper
Never store passwords in:
- Unencrypted text files or documents
- Browser password managers (except as secondary backup)
- Physical notebooks (unless kept in a very secure location)
Yes! Our advanced password generator is completely free to use with no hidden costs or limitations.
We support the service through:
- Non-intrusive advertising (you can optionally disable with an ad blocker)
- Affiliate links to recommended security products (never affects our recommendations)
- Community support and donations
We will never:
- Charge for basic password generation features
- Sell your data (we don't collect passwords or personal information)
- Add paywalls to essential security features
The tool works entirely in your browser - you can even save this page for offline use!
