How to generate a strong password
Select the character groups you want, choose a length, and click Generate passwords. Each result is produced using the browser's cryptographically secure random number generator (crypto.getRandomValues), with an unbiased selection algorithm. Every enabled character group appears at least once.
What makes a password stronger?
Long, unique passwords are generally harder to guess. A 16–20 character random password is a practical choice for many accounts when the website allows it. Avoid reusing passwords, and enable multi-factor authentication where available.
Frequently asked questions
Are passwords sent to ToolsFire?
No. Passwords are generated on your device in the browser. This tool does not send, save or log them.
Can I exclude confusing characters?
Yes. Enable the exclusion options to remove visually ambiguous characters from the available sets.
How many passwords can I generate?
Generate between 1 and 50 passwords at a time. Each can contain 8 to 128 characters.
Is the strength estimate a guarantee?
No. The displayed entropy is a theoretical estimate based on the selected character pool. Real-world security also depends on how passwords are stored and used.
