How strong is a 16-character password?
Sixteen characters is the sweet spot for anything important: comfortably beyond brute force, still short enough to type occasionally if you must.
With the character sets shown above, each position is drawn from a pool of 94
possibilities, so this password carries roughly 105 bits of entropy —
about 1032 equally likely combinations. Every character comes
from crypto.getRandomValues() using rejection sampling, so there is no
modulo bias skewing the result. Press the button above to generate a fresh one; the
entropy and crack-time figures update live if you change the length.
Want a different length or a memorable alternative? The full password generator lets you set any length from 8 to 128, and the passphrase generator builds word-based secrets that are easier to type. To see why a longer password is exponentially harder to crack, read how password entropy works.
