Pro Tip: Use Incognito Mode

For maximum security, we recommend using this tool in a Private/Incognito window. This prevents third-party browser extensions from reading your keystrokes.

Stop using weak passwords.

Check if your password has been leaked in a data breach or generate a cryptographically strong passphrase.
