What makes a password strong

Length matters most. Each extra character multiplies the number of possible passwords, so a 16-character random password is far stronger than an 8-character one with symbols. Mixing upper and lower case letters, numbers and symbols helps further. The strength bar estimates how hard the password would be to guess by brute force.

Look-alike characters such as l, I, O, 0 and 1 are left out by default so the password is easier to read and type. Include them if you only ever paste the password.

Keeping passwords safe

Use a different password for every account, so one leak does not unlock the others. A password manager can store them for you, and turning on two-factor authentication adds another layer of protection.

Every password here is created in your browser. Nothing is sent over the network or saved, so not even we can see it.

Frequently asked questions

Are these passwords really random?

Yes. They use your browser's cryptographically secure random number generator.

Is the password sent or stored anywhere?

No. It is created on your device and never leaves it.

How long should a password be?

At least 12 characters, and 16 or more for important accounts.

Why are some characters missing?

Look-alikes such as l, I, O, 0 and 1 are skipped by default to avoid typing mistakes. You can turn them back on.
