Frequently Asked Questions
Is this password sent or stored anywhere?
No! It is generated in your browser memory via Web Crypto and never touches a network connection. As soon as you close or refresh the tab, it disappears from memory.
How long should a strong password be?
For critical accounts, we recommend at least 16 to 24 characters containing mixed case, digits, and symbols.
