Password generator
Generate strong passwords with configurable charsets, a "no look-alikes" mode, an entropy bar and a crack-time estimate — backed by crypto.getRandomValues.

/tools/password generates passwords up to 128 characters from any subset of lowercase, uppercase, digits and symbols. Toggle “No look-alikes” to strip i l 1 L o 0 O for passwords meant to be typed off a printout.
Randomness comes from crypto.getRandomValues — cryptographically secure, browser-native — with rejection sampling on the bytes to keep the modulo unbiased across non-power-of-two alphabet sizes.
Below the password you get the entropy in bits and a rough crack-time estimate calibrated at 100 GH/s (top-end modern GPU). The colour-coded bar gives a quick “is this strong enough” verdict: red below 28 bits, amber 28-50, yellow 50-75, green 75-100, teal 100+.
Privacy detail worth noting: the share link encodes your settings, not the password. If you tweak the charset to your taste, you can share the configuration without leaking any generated value.
