Password Generator
A strong password is the first line of defense for your online accounts. This generator creates secure random passwords with the length and character sets you choose, and instantly measures their strength in entropy bits. Everything is generated inside your browser — nothing is sent to any server.
How to use
- Set the password length with the slider (4 to 64 characters).
- Choose the character types: uppercase, lowercase, digits, symbols, and optionally exclude similar characters.
- Press Generate to see the password with its strength meter.
- Press Copy to copy it and use it right away.
Frequently asked questions
What makes a password strong?
Length first, then variety. A 16-character password mixing letters, digits and symbols is far stronger than a short complex one. The meter measures entropy in bits — the higher the number, the harder the password is to guess.
Are generated passwords stored or sent anywhere?
No. Generation happens entirely in your browser using the secure crypto random generator, and no character ever leaves your device.
Why exclude similar characters?
Characters like I, l, 1, O and 0 are hard to tell apart when typing manually, so excluding them makes passwords easier to transcribe without mistakes while staying strong.
How long should my password be?
12 characters is an acceptable minimum; 16 or more is recommended for important accounts with all character types enabled, ideally stored in a password manager.
