Frequently Asked Questions
How is this different from the regular Password Generator?
This tool always requires every character type and defaults to a longer minimum length, aimed at accounts that need maximum protection.
Why are characters like 0 and O excluded?
They're visually similar and easy to mistype or misread, so they're left out to reduce entry errors.
Is 20 characters overkill?
For most personal accounts it isn't necessary, but for admin, financial, or master passwords, longer is safer.
Does this tool save my password?
No, nothing is stored or transmitted; the password only exists in your browser until you navigate away.
