Quick start
- Choose a length. Longer is usually stronger.
- Choose which character types are allowed.
- Use avoid ambiguous characters when you need to type or read the password manually.
Best uses
Use this guide when one of these tasks matches what you are trying to do.
- Create a unique password for a new account.
- Generate longer passwords for password manager storage.
- Avoid ambiguous characters when reading a password aloud or typing it manually.
- Estimate password strength from length and character pool size.
What the calculator is doing
The generator builds a character pool from your choices and uses browser cryptographic random values to choose each character.
How to read the answer
After calculating, read the main answer first, then use the supporting metrics to understand the context.
- The password is the main answer and can be copied.
- Entropy is an estimate based on length and character pool size.
- The tool does not add generated passwords to recent history.
Common mistakes to avoid
Most wrong answers come from using the wrong unit, date, weight, scale, or policy assumption.
- Do not reuse generated passwords across accounts.
- Do not paste passwords into untrusted pages.
- Do not rely on memory for long random passwords; use a password manager.
