Frequently asked questions
Is this password generator free?
Yes. You can generate passwords for free without creating an account.
Are my passwords uploaded or saved?
This tool generates passwords in your browser. It does not send them to a NinaTools server or intentionally save them. If you copy a password, it may remain in your device's clipboard until replaced.
How long should my password be?
A longer, unique password is generally preferable. A length of 16 or more characters is a useful starting point for many accounts, but follow the account provider's requirements.
Is this generator suitable for important accounts?
