About Password Generator
Every password includes at least one character from each kind you turn on, then the rest is chosen uniformly at random. “Avoid look-alikes” drops characters such as l, 1, O and 0 for passwords you have to type by hand. The time to guess assumes a fast offline attack of 100 billion guesses a second.
Values come from the browser’s cryptographic random generator (crypto.getRandomValues) on this device. Nothing is sent or stored, so no one else ever sees them.
