Frequently Asked Questions
Is this secure?
Yes, it uses `crypto.getRandomValues` (Web Crypto API) for cryptographically secure randomness, unlike `Math.random()`.
Can I use custom characters?
Yes, enter any specific characters in the "Custom Characters" field and the generator will only pick from those.
Is there a length limit?
There is no hard limit, but browser memory may constrain extremely long strings (millions of chars).
