Password Generator & Strength Checker

A secure password generator creates unpredictable passwords from cryptographically strong random values instead of ordinary predictable pseudo-random functions. This page uses the browser security interface and does not silently fall back to weaker randomness.

The generator creates new random passwords or passphrases. The strength checker evaluates a password you enter and reports length, character variety, common patterns and practical recommendations without generating a replacement automatically.

The generator builds a permitted character pool from your selected options, obtains cryptographically strong random integers, chooses characters without modulo bias and securely shuffles required character groups into the result.

No. Secure password generation is disabled when cryptographically strong browser randomness is unavailable. The page does not substitute ordinary non-cryptographic randomness.

For most accounts, a unique password of at least 15 or 16 characters is a practical starting point when the service allows it. Longer passwords and passphrases generally provide more guessing resistance, especially when they are randomly generated.

Not every service requires composition rules, and length is usually more valuable than forcing predictable substitutions. The generator supports character-group rules because many websites require them, but a long unique password remains the main objective.

A random password usually combines characters from several sets. A passphrase combines several randomly selected words, often separated by hyphens or spaces, which can be easier to type while remaining long.

Six or seven independently selected words from a sufficiently large list is a practical default for many uses. This page shows the word-list size and an upper random-selection estimate so you can compare settings.

Yes. Choose the PIN preset or enable only numbers. A PIN has a smaller search space than a long password, so use the longest PIN the destination permits and rely on account lockout or device protections where available.

It removes commonly confused characters such as uppercase I, lowercase l, the number 1, uppercase O and the number 0. This improves manual readability but slightly reduces the available character pool.

It removes symbols that are often difficult to distinguish, quote correctly or enter on some keyboards. The exact remaining symbol set is shown by the selected options.

Yes. Enable Start with a letter. The generator will securely choose the first character from an enabled letter group and generate the remaining positions from the full permitted pool.

Yes. Enable No adjacent repeats. Each new character is then selected from the permitted pool excluding the immediately previous character when possible.

It changes the distribution because at least one character is reserved for each required group, but the remaining positions are still selected securely and the completed password is securely shuffled. The option is useful for websites with composition requirements.

The checker combines length, character variety and uniqueness with penalties for common passwords, repeated chunks, keyboard paths, obvious sequences, dates, years and common words. It is a practical estimate rather than proof that a password is safe.

It is an upper estimate based on the character groups observed and the password length. Human-selected passwords are rarely uniformly random, so the page also applies pattern penalties and never presents the number as guaranteed entropy.

No. They are illustrative comparisons based on selected guessing rates and the adjusted estimate. Real attack speed depends on password hashing, hardware, rate limits, breach data, attacker strategy and whether the password follows a known pattern.

No external breach lookup is performed. The page checks a compact local list of common passwords and patterns, but it cannot confirm whether a specific password appears in a breach database.

The page-specific checker evaluates text in the current browser and does not send it to a password-checking service. Even so, use a trusted device, keep the page secure and reset the field when finished.

No page-specific request sends generated passwords or checker input to a server. Results remain in the current page session and disappear when the page is reset, reloaded or closed.

No. The page does not use page-specific local storage for generated passwords or strength-checker input. Only the current in-memory results are available until reset or page closure.

Yes. Download TXT saves the currently generated list as plain text. Plain-text password files can be exposed by backups, file syncing, malware or other users, so store or delete the file carefully.

Yes. Generated password and passphrase list filenames begin with correctioncopy.com_ and use a meaningful text filename. Strength reports use the same prefix and exclude the password itself.

Yes. Choose a quantity from 1 to 20. Duplicate results are rejected and regenerated when practical.

Yes. Enter a custom symbol set. Duplicate characters are removed automatically, and excluded characters are removed from every selected group before generation.

Generation stops and the page asks you to enable at least one character group. It does not produce an empty or misleading result.

The browser security interface may be unavailable, restricted by the environment or interrupted. Use a current browser and a normal top-level page. The tool will not use a weaker random fallback.

Yes. Generator settings, results, copy actions, strength analysis and help sections adapt to touch screens and narrow mobile layouts.

Current Chrome, Edge, Firefox and Safari versions normally support the required secure random interface. Clipboard and downloaded-file behavior can vary with browser permissions and device settings.

No. A password can be strong against guessing but still unsafe when reused. Use a different password for every important account so one breach does not expose several services.

A reputable password manager can generate, store and autofill unique passwords so you do not need to memorize every random value. Protect the manager with a strong master password and multi-factor authentication where available.

No. Multi-factor authentication adds another defense, but a unique strong password still reduces account takeover risk when another factor is unavailable, bypassed or socially engineered.

Press Reset All. It restores the balanced generator preset, clears generated values, clears the strength-checker field and removes temporary download data.
