Strong Password Generator
Generate cryptographically secure random passwords with configurable length, character groups and ambiguous-character filtering.
Why use this strong password generator?
Strong Password Generator uses the browser cryptography API, guarantees inclusion from each selected character group and avoids modulo bias when choosing random characters. You can also exclude easily confused characters.
Example
Generate a 24-character password using uppercase, lowercase, numbers and symbols, then copy it directly into a password manager.
Important note
Use a password manager and a unique password for each account. Estimated entropy is a mathematical indication, not a guarantee against every attack or compromised device.
How to use it
Start with the inputs shown above, review the assumptions or options, then generate the result. Where the tool creates a file, keep the original until you have opened and checked the downloaded output.
