Frequently asked questions

How long should a password be?

At least 14–16 random characters for important accounts. Length matters more than symbols; every extra character multiplies the work for an attacker.

Should I reuse a strong password?

No. Use a different password for every site and keep them in a password manager — one leaked site should not unlock the others.

Is my data sent anywhere?

No. Everything is calculated in your browser on your own device — nothing you type or upload is sent to a server.
