Frequently Asked Questions About Password Generator
What makes a password strong?
A strong password is long (16+ characters), uses a mix of character types (uppercase, lowercase, numbers, symbols), contains no dictionary words or personal information, and is unique per account. Our generator creates passwords that meet all these criteria.
Is the password generation secure?
Yes. All passwords are generated in your browser using the Web Crypto API's cryptographically secure random number generator. The generated password never leaves your device and is not stored or transmitted anywhere.
What are ambiguous characters?
Ambiguous characters are those that look similar and can be confused: zero (0) and capital O, one (1), lowercase l (l), and capital I (I). Excluding them makes passwords easier to read and type manually.
