Password Generator - Cryptographically Random, Fully Local
Create strong random passwords with adjustable length, character sets, and a live entropy readout.
Randomness You Can Actually Trust
Most web password generators either ship your settings to a server or rely on predictable JavaScript randomness. AiLoveKit's password generator draws every character from crypto.getRandomValues - the browser's cryptographically secure random number generator - with rejection sampling to avoid modulo bias. The result is displayed, never transmitted.
What Makes a Password Strong
- Length first - every extra character multiplies the search space; 16+ is a solid baseline.
- Mixed character sets - upper, lower, digits, and symbols widen the pool each position draws from.
- Entropy readout - the tool shows the bit strength live; aim for at least 80 bits, 100+ for important accounts.
Store generated passwords in a reputable password manager - never reuse one across sites.
