Strong passwords without guesswork
Anyone creating a new login can use this generator to produce a long, unpredictable password instead of reusing a memorable phrase. Random values come from the browser’s cryptographic random-number generator, which is designed for security-sensitive tasks.
A practical example
Choose 20 characters with uppercase, lowercase, numbers, and symbols to create a password with a broad character pool and an estimated entropy readout. The exclude-ambiguous option helps when a password must be typed from another screen.

A simple, local workflow
- 1Choose the password length and the character groups you want to allow.
- 2The browser generates cryptographically random values and maps them to the selected character pool.
- 3Review the estimated entropy, then copy the generated password into a trusted password manager.

FAQs
Common questions
What password length should I use?
For most accounts, 16–20 random characters is a strong practical target; use the maximum allowed for especially important accounts.
What does estimated entropy mean?
Entropy estimates how many bits of uncertainty a truly random password contains. More length and a larger character pool increase it.
Why exclude ambiguous characters?
Characters such as uppercase I, lowercase l, the number 1, uppercase O, and zero can be hard to distinguish when copied by hand.
Should I save the generated password?
Yes—store unique passwords in a reputable password manager rather than in an unencrypted note or screenshot.
