  2. Choose character typesMore variety means more strength — keep symbols on unless a site forbids them.
  3. Generate and copyEach click creates a new password using crypto-grade randomness.

Frequently asked questions

How long should a password be in 2026?

At least 16 characters for anything important. The UK's National Cyber Security Centre also endorses three random words (e.g. from a passphrase) as a memorable alternative for accounts you type often.

Is it safe to generate a password online?

Here, yes — generation uses your browser's crypto.getRandomValues() locally. The password never leaves your device, isn't logged, and we can't see it.

Should I use the same password on multiple sites?

No — reuse is the single biggest password risk. If one site is breached, attackers try that password everywhere. Use a password manager so every account is unique.

Are random passwords better than memorable ones?

Random is stronger per character, but the best password is one you'll actually use uniquely — a password manager plus random passwords, with a strong memorable passphrase protecting the manager itself, is the standard recommendation.
