Questions
Is this password generator safe?
The password is made in your browser with crypto.getRandomValues, the secure random numbers every browser has, and an unbiased way of picking each character. It is never saved, never put in a link and never sent anywhere. There is no Share button on this page.
What do the bits mean?
Bits count how many passwords these settings could have made: 60 bits is about 2 to the power 60, a billion billion. Each extra bit doubles the guesses an attacker needs. It is worked out from how the password was made, so it is honest.
How strong should a password be?
For most accounts, 60 bits or more, which the default password and a six-word passphrase both give. For a password manager or anything precious, aim for 80 or more. Use a different password for every site.
Password or passphrase?
A passphrase of random words is easier to type and to remember, and six words is about as strong as a 10-character password. A password packs more strength into fewer characters.
What are look-alikes?
Characters that are easy to misread: 0, O and o, and 1, l, I and |. Leave them out when someone has to read the password off a screen or a card.
