Frequently asked questions
How long should a password be?
Use at least 14 to 16 characters for important accounts. Longer random passwords are much harder to guess.
Is the password stored?
No. It exists only on this page until you copy it or leave.
Why exclude ambiguous characters?
Characters such as 0/O and l/1 are easy to misread when typing a password by hand.
