how to wifi password generator
- pick a mode: random, pronounceable or memorable words.
- set the length and the character types, and choose how many passwords you want.
- check the strength meter and the estimated crack time.
- copy one password, copy all, or download the list as a .txt file.
wpa2 and wpa3 allow passwords of 8 to 63 characters. the router password protects against anyone nearby who captures the handshake and then tries guesses offline, so length is the best defense. 16 letters and digits give about 90 bits, and 20 give over 110 bits.
look-alike characters such as 0 and O, or 1, l and I, are removed so the password can be read from a card on the fridge without mistakes. symbols are off by default because phone keyboards hide them and some smart devices handle them badly. pair this with a wifi qr code so guests can join by scanning.
