About this tool
Choose a length and character sets to generate passwords with the browser's cryptographically secure random number generator. Every selected set is represented, ambiguous characters can be removed, and multiple passwords can be generated at once.
Each selected character set appears at least once. The length must not be shorter than the number of selected sets.
Random bytes use rejection sampling to avoid modulo bias, followed by a secure Fisher–Yates shuffle.
Generated passwords are not stored or transmitted. Use a unique password per account and enable multifactor authentication when available.
FAQ
- How long should a secure password be?
- The required length depends on the service and use case. This generator supports 4–128 characters; use a sufficiently long, unique password within the destination's rules.
- Are generated passwords sent anywhere?
- No. They are produced with cryptographic randomness inside the browser and are not stored when the page is closed.
- Can I generate a password without symbols?
- Yes. Clear the symbols option to use only the other selected character sets. Enable symbols when the destination requires them.
- Can ambiguous characters such as 0 and O be excluded?
- Yes. The exclusion option removes 0/O and 1/l/I from the candidate sets, including the required character selected from each enabled set.
