Hoe we veilige wachtwoorden genereren
Creating a strong password is more than combining random characters. At PrivateNote.ai, our generator is built around three principles:
Cryptographic Security
Using the same class of secure randomness used for keys and tokens.
Unbiased Randomness
Every character has an equal chance of being selected.
Intelligent Strength Analysis
Advanced analysis beyond simple length checks.
Here is how each component works to keep your accounts secure.
Crypto Web API
The generator uses the Web Crypto API to acquire cryptographically secure random values suitable for security-critical work.
The randomness is seeded by the operating system and designed so future values cannot be predicted in practice without access to internal state.
All generation happens in your browser. Your password never leaves your device, so it cannot be logged, intercepted, or leaked from our servers.
Why this matters: Server-side password generation creates extra exposure through network transit and logs. Local generation avoids those risks entirely.
Unbiased Randomness
We use rejection sampling so every character has the same chance of appearing. That removes subtle bias that can make some characters more likely than others.
Simple modulo selection can be biased when the random number range does not divide evenly by the character set size. Rejection sampling discards unfair values and draws again.
This makes passwords harder to predict because attackers cannot exploit character-selection patterns.
Smart Strength Analysis
A strong meter should look beyond length and symbol rules. Predictable strings can look complex while still being weak.
We use zxcvbn-style analysis to check common patterns, dictionary words, sequences, repeated characters, entropy, and realistic crack-time estimates.
That gives you a more realistic view of password strength than a simple checklist.
- Common patterns: keyboard paths, sequences, and repeated characters
- Dictionary attacks: common words, names, and breached-password variations
- Entropy: how much of the password is actually unpredictable
- Crack time: how long an attacker would realistically need
Password Best Practices
- Use unique passwords: Never reuse passwords across accounts.
- Longer is better: Aim for at least 16 characters; more is better for high-value accounts.
- Use a password manager: Store generated passwords securely so you do not have to remember them.
- Enable two-factor authentication: Even strong passwords benefit from an extra layer.
- Do not share passwords: Never share passwords with anyone claiming to be support.
