Frequently asked questions
How secure are the generated passwords?
They are generated using cryptographically strong pseudo-random number generators, making them virtually impossible to brute-force when 16+ characters long.
Are generated passwords saved in history?
No. Passwords exist only in your current session memory and disappear as soon as you close or refresh the tab.
What is the recommended password length?
Security experts recommend a minimum length of 16 characters including letters, numbers, and symbols.
