Strong passwords depend on length and unpredictability
A secure password should be closer to random characters than to a memorable word, and it should be unique per service. This browser-side generator lets you adjust length, character classes, ambiguous characters, and entropy-based strength.
Key concepts
Character pool
Uppercase, lowercase, numbers, and symbols increase the search space.
Unique use
Reusing one password turns a single breach into a multi-account risk.
How to use
- Set the length and choose the character types.
- Exclude ambiguous characters if readability matters.
- Copy the result into a password manager.
Frequently asked questions
How long should it be?
Use at least 16 characters when possible. Longer is usually better.
Do I need symbols?
It depends on the service, but symbols increase the character pool and entropy.
Should I memorize generated passwords?
For long unique passwords, a password manager is the practical option.
Store passwords in a trusted manager and enable multi-factor authentication where possible.
