Strong Password Generator
Generate random passwords in the browser with crypto.getRandomValues—length 4–128, charset options, heuristic strength only. The UI does not call the server GeneratePassword endpoint.

Generated Passwords
Tips
Client-side randomness
Passwords are built with crypto.getRandomValues in your browser. This UI does not call the server GeneratePassword endpoint.
Length 4–128
Choose a length in that range; prefer 12+ characters when a service allows it.
Strength is heuristic
Entropy and “time to crack” labels are estimates for guidance—not a measured crack time against a real attacker model.
Use a password manager
Store unique passwords safely and enable multi-factor authentication where available.
crypto.getRandomValues
Random bytes come from the Web Crypto API in supporting browsers.
Charset options
Toggle lowercase, uppercase, numbers, symbols, and exclusion options.
Heuristic strength meter
Shows estimated strength/entropy-style indicators—not true crack time.
No GeneratePassword API from this UI
Generation on this page stays in the browser and does not call Toolomix GeneratePassword.
What this tool does
Strong Password Generator creates random passwords in your browser with crypto.getRandomValues, using length 4–128 and the character-set options you select.
Strength indicators are heuristic. This page does not call the server GeneratePassword endpoint.
How to use
Set length and character types
Choose length (4–128) and enable lowercase, uppercase, numbers, and/or symbols.
Adjust advanced options
Optionally exclude similar/ambiguous characters or require all selected types.
Generate and copy
Create one or several passwords, then copy them into a password manager.
Supported inputs and output
Input: configuration only (length, character sets, advanced toggles)—no password upload. Output: one or more generated password strings plus heuristic strength indicators.
There is no file-based password workflow.
Processing and privacy
Generation uses crypto.getRandomValues in your browser.
This UI does not call Toolomix GeneratePassword. Generated values are not sent to Toolomix as part of that client-side generation flow.
Limitations
Known limits
- Length limited to 4–128
- Requires a browser that supports crypto.getRandomValues
- Strength / time-to-crack display is heuristic, not true crack time
- UI does not call server GeneratePassword
- Does not replace multi-factor authentication or unique passwords per account
Troubleshooting
If generation fails, confirm your browser supports the Web Crypto API (crypto.getRandomValues) and that at least one character type is selected.
If strength looks surprising, treat it as a rough heuristic—adjust length and charset rather than trusting “time to crack” as literal.
Frequently Asked Questions
Does this call GeneratePassword on the server?
No. This UI generates passwords in the browser with crypto.getRandomValues and does not call the Toolomix GeneratePassword endpoint.
Are passwords uploaded or stored?
Generation for this page runs locally. Toolomix does not receive the generated password as part of that client-side flow.
What length is supported?
Length can be set from 4 to 128 characters.
Is “time to crack” accurate?
No. It is a heuristic estimate for rough guidance, not a true crack-time calculation.
What provides the randomness?
crypto.getRandomValues from the browser Web Crypto API (in supporting browsers).
Can I exclude confusing characters?
Yes. Use the options to exclude similar or ambiguous characters when available in the UI.
Can I generate several passwords at once?
Yes. The UI supports generating multiple passwords in one run (for example five).
