Generate strong passwords and memorable passphrases

Create unbiased random passwords or multi-word passphrases, see the estimated entropy, and copy one or many results — everything runs locally with the Web Crypto API.

Count

Use one result for quick copy, or generate a batch when needed.

OutputStrength: Strong
Estimated entropy: 117 bits

Quick answer

AppHelp generates strong random passwords and memorable passphrases locally with the browser Web Crypto API. Choose password or passphrase mode, review the estimated entropy, generate one or many values, and store the result in a trusted password manager instead of reusing it.

How to use

  1. 1. Choose password or passphrase modeUse Password for compact credentials with character rules. Use Passphrase for longer, easier-to-read word-pair sequences when the service accepts them.
  2. 2. Set the security controlsFor passwords, choose length and character classes. For passphrases, choose the number of independently generated word pairs and a separator.
  3. 3. Check the entropy estimateThe estimate reflects the configured search space. Prefer a strong result and follow any length or character restrictions imposed by the destination service.
  4. 4. Generate, copy, and store safelyGenerate the requested count, copy the results, and save each credential in a password manager. Do not reuse generated passwords across accounts.

Examples

Website password

Input
20 characters; lowercase, uppercase, digits, and symbols; ambiguous characters excluded
Output
A different 20-character random password on every generation

The output is nondeterministic because it comes from Web Crypto.

Readable passphrase

Input
6 word pairs separated with hyphens
Output
Example shape: amberFalcon-quietRiver-cobaltForest-…

Each compound token is selected from independent adjective and noun pools.

Bulk credential setup

Input
Count: 10
Output
Ten independently generated values, one per line

Common use cases

  • Create a unique password for a new website or application account
  • Generate service, API, database, or Wi-Fi credentials that meet specific character rules
  • Create readable passphrases for accounts that permit longer credentials
  • Produce several independent temporary credentials for a controlled setup workflow
  • Compare how length and alphabet size change estimated entropy

Edge cases

  • A strong generated password still needs unique storage; reuse turns one breach into several compromised accounts
  • Some legacy forms reject long passwords, spaces, or particular symbols even when those choices improve entropy
  • The entropy badge describes the generator's theoretical search space, not the security of the destination service or device
  • Passphrase word pairs are machine-generated compounds, not quotations or personal phrases, so do not replace them with predictable names or lyrics
  • Clipboard contents may be readable by other software on the device; paste into the destination or password manager and clear sensitive clipboard history when appropriate

Features

  • Generate random passwords from 4 to 64 characters with required character-class coverage
  • Generate readable passphrases from independently selected adjective and noun pairs
  • Use the Web Crypto API with rejection sampling for unbiased random choices
  • Exclude ambiguous characters, generate up to 50 values, and copy results in one action
  • See an entropy estimate before generating without sending secrets to a server

Frequently asked questions

Are the passwords cryptographically secure?
Yes. Characters and word components are chosen with the Web Crypto API using rejection sampling for unbiased selection.
What is the difference between password and passphrase mode?
Password mode builds a compact credential from selected character classes. Passphrase mode combines independently chosen adjective and noun pairs into a longer value that can be easier to read.
What does the strength rating mean?
It estimates entropy in bits from the configured generator space: under 50 is weak, 50 to 80 is medium, and over 80 is strong. It cannot measure server security, malware, reuse, or unsafe storage.
Should I save the generated password in this page?
No. Copy it into a trusted password manager. AppHelp does not keep a password vault or recover values after you clear or close the page.
Does AppHelp upload generated passwords?
No. Generation and entropy calculation happen entirely in your browser, and the dynamic output is not intended for search indexing.
