About Random string generator

Frequently asked questions
Is this random string safe for passwords?
It uses the browser's cryptographic random source and runs locally, so it is suitable. For important accounts, make it long and store it in a password manager.
How long should a random code be?
Longer is harder to guess. For codes and tokens, more characters and a wider mix of letters, numbers and symbols give more possible combinations. Match the length to what the system accepts.
Why should I avoid look-alike characters?
Letters like O and 0 or l and 1 are easy to mix up when typed by hand. If people will read the code aloud or type it, leave out confusing characters.
