About this generator
This generator creates strong random passwords directly in your browser, drawing each character from the browser's native cryptographic API — the same one used by systems that need truly secure randomness, never a common pseudo-random number generator, which isn't designed to produce secrets. All generation happens locally: no password generated here is ever sent, stored, or logged on any server, not even Nexinon's own.
Frequently asked questions
It's a measure of how many different combinations a password could have, given its length and the character types chosen — each extra bit doubles that number. A password with 80+ bits of entropy is considered robust even against dedicated cracking hardware.
Only if you'll type the password manually at some point — from a piece of paper, or on a device without copy/paste access. Characters like 0/O or 1/l/I are easy to mix up visually. If you only copy and paste the password, leaving the option off keeps the character pool larger (more entropy), with no practical downside.
No. All generation happens in your browser — no character generated here ever travels over the network, gets stored, or is logged anywhere, not even on Nexinon's own servers.
It depends entirely on where the generation happens. A generator that processes everything in your browser (like this one) never exposes the password to the network; one that generates it server-side and sends it back to you already introduces a risk point — even a trustworthy service means the password traveled somewhere beyond just your computer.
Generally, yes — length is the single biggest factor in entropy. But there's a practical limit: systems that cap the character count (some forms still limit to 16 or 20) make longer passwords pointless there. For most cases, 16 characters with every character set enabled already produces a very strong password.
Yes, whenever the destination system accepts them — each additional character set (uppercase, lowercase, numbers, special) grows the pool size and, with it, the password's entropy. The exception is when the destination system itself doesn't accept symbols, which still happens occasionally.
