Frequently Asked Questions
How does this tool generate random passwords?
It uses the browser's crypto.getRandomValues() API for cryptographically strong randomness—not Math.random(). That is the right approach for unpredictable passwords.
What makes a password strong?
Length and variety (upper, lower, digits, symbols) increase entropy. Avoid predictable words and personal details. The strength meter reflects how hard the password is to guess.
How long should a secure password be?
Aim for at least 12 characters for everyday accounts and 16+ for email, banking, or password managers. Longer is generally better than complex-but-short.
Are generated passwords stored or sent online?
No. Generation runs only in your browser; passwords are not logged or uploaded. Copy what you need before leaving the page.
Should I use a password manager?
Yes. Unique strong passwords per site are impractical to memorize; a reputable password manager stores them safely so you do not reuse weak passwords.
