Generate a password you control

Set the length, pick which character types to include, and exclude look-alike characters if you will be typing the password off a screen. The strength indicator shows the actual entropy in bits and explains what would improve it — but it never stops you: if a system demands exactly eight digits, this will generate exactly eight digits and tell you honestly how weak that is. Passwords are produced on your device with the browser's cryptographic random number generator, never with a general-purpose one, and they never leave this tab.

This is processed on your device and never sent anywhere. Nothing you paste here leaves this tab, and nothing is saved after you close it.

How many

StrengthVery strong

about 130 bits of entropy, from a 90-character alphabet

Bands: under 40 bits is weak, 40–59 fair, 60–79 strong, 80 and above very strong. These boundaries follow common convention rather than a measurement.
