Frequently asked questions

Does PasswordCraft save my passwords?

No. Passwords exist in browser memory only. Only your theme preference is saved.

Can a strength score guarantee safety?

No. Guessability is one factor. Use unique credentials, protect recovery channels, and enable multifactor authentication or passkeys.

Why doesn’t Copy work in my browser?

Clipboard permissions and secure-context requirements vary. If copying is blocked, select the displayed result and copy it manually.
