When to use a random PIN
Random PINs are better than birthdays, repeated digits, addresses, and easy patterns. Use longer PINs when the system allows it.
The tool runs in your browser. Passwords are not transmitted, stored, logged, placed in analytics, or added to any URL.
PIN safety basics
Do not reuse important device PINs across accounts or services. Avoid writing PINs where other people can find them.
For high-risk accounts, use a long password, passkey, or multi-factor authentication instead of relying on a short PIN alone.
