よくあるご質問 (FAQ)
Q: Are the generated passwords cryptographically secure?
A: Yes. They are generated using the browser's native cryptographic random number generator (CSPRNG), which provides high-entropy randomness suitable for security keys.
Q: What does 'Exclude Ambiguous Chars' do?
A: It filters out characters that look similar in many fonts, such as uppercase 'I', lowercase 'l', and number '1', or 'O' and '0'. This makes it much easier to read and type manually.
Q: Can I limit the punctuation characters used?
A: Yes. When the symbols checkbox is active, you can edit the symbol set in the text box. Add or remove characters to match the password policies of specific websites.
