Password and passphrase generator.

Strong, random, and made on your device. Never sent, never stored.

Runs in your browser. Uses your device's secure random generator.

Make a password What makes it strong

Generator

Random on purpose.

Choose a type, adjust it, and see how long it would really take to crack.

Length20

Lowercase (a-z) Uppercase (A-Z) Numbers (0-9) Symbols (!@#$...) Avoid look-alikes (I l 1 O 0 o) Include at least one of each type

Never use these characters

How long to crack itaverage case

Estimates assume the attacker knows how it was made and must try every possibility. Real speeds vary, so treat this as a guide.

What makes it strong

Length beats cleverness.

Truly random

No bias.

Every character is picked with the browser's secure random source, using a method that avoids the tiny bias many generators have. No patterns, no seed, no history.

Honest numbers

Bits of entropy.

Each extra bit doubles the work for an attacker. 80 bits is strong. 100 bits is beyond any attacker today.

Private

Nothing leaves.

It is made on your device. Nothing is sent, logged or stored, and it disappears when you close the page.

Reusing a password.One breach exposes every account that shares it. Use a different one everywhere, and keep them in a password manager.

Clever substitutions.P@ssw0rd tricks are in every cracking list. Random beats clever, every time.

Short and complex.Length matters more than symbols. A five-word passphrase is easier to remember and stronger than most 10-character passwords.
