Questions
How long should a password be?
The length is up to you. This tool goes from 8 to 128 characters, and 20 is the default. A longer password has more bits of strength.
What does the strength in bits mean?
It is worked out from the length and the number of possible characters. More bits means more possible combinations.
Is the password saved or sent anywhere?
No. The password is made in your browser and is not saved or sent anywhere. Copy it somewhere you trust before you close the page.
Why can I leave out some characters?
The option that avoids look-alike characters removes 0, O, l, 1 and I, which are easy to mix up when you type or read a password.
