Generation fails
enable at least one character set and ensure the length can satisfy any enforced “include each selected type” rule.
Password Generator
Create unique password candidates with explicit length and character settings—without claiming cryptographic security before the random source is audited.
Developer & Text ToolsDirect answer
Password characters use crypto.getRandomValues with rejection sampling. The tool generates 1, 3, 5 or 10 passwords of 8 to 128 characters; the strength label is an entropy estimate, not a breach or phishing check. Configurable password length and output count.
Generated passwords
Create secure random passwords locally in your browser.
Estimated strength:Excellent(127 bits)
Options
How to use it
Enter the source data: Choose a length and the required lowercase, uppercase, number and symbol sets. Follow the destination service’s actual password policy rather than maximizing every option blindly.
Choose the relevant settings: Set the number of candidates and optionally exclude visually ambiguous characters. Generate only after confirming that at least one usable character set remains.
Review and verify the result: Select one unique password, store it directly in a trusted password manager and clear any visible/history/clipboard residue. Never reuse it across accounts.
Key capabilities
- Configurable password length and output count.
- Separate lowercase, uppercase, digit and symbol controls.
- Option to exclude ambiguous characters.
- Visual strength estimate with non-guarantee wording.
- Copy one or all generated candidates.
Best use cases
- Create test credentials for non-production fixtures.
- Generate a unique password that satisfies a known service policy.
- Demonstrate how length and character-set constraints affect the search space.
Limits and safety notes
- Use sample or non-production data. The current page describes local processing, but sensitive secrets still require an independent code and network audit before this can be treated as a security guarantee.
Troubleshooting
Password is rejected by a service
use that service’s exact allowed-symbol and maximum-length rules.
Copied password appears in clipboard history
clear it and rotate the credential if exposure is possible.
Frequently asked questions
What makes a password strong?
For generated passwords, sufficient length, uniqueness, an unpredictable random source and safe storage matter more than a decorative strength label. Never reuse passwords.
How long should a generated password be?
Use the longest random password the service and password manager reliably support, subject to policy. A fixed universal length should not be promised for every risk model.
Is the generator cryptographically secure?
The core transformation runs in the current browser component. Browser extensions, clipboard history, downloaded files and site-wide diagnostics remain separate exposure points, so never enter production secrets unless you have reviewed the complete environment.
Is it safe and private?
Short answer: Use sample or non-production data. The current page describes local processing, but sensitive secrets still require an independent code and network audit before this can be treated as a security guarantee.
Does it work on mobile?
The layout adapts to narrow screens. File selection, camera access, clipboard actions and downloads still depend on the permissions and capabilities of the mobile browser.
