Frequently asked questions
Is my password uploaded to a server?
No. The strength analysis happens locally in your browser. The password is not submitted to NextWatch AI.
What does the strength rating mean?
It estimates guessability from length, common patterns, sequences, keyboard patterns and repetition. It cannot prove a password is uncrackable or that it has not been leaked.
What is the best way to improve password security?
Choose a unique random password, enable multifactor authentication and use a password manager. Never reuse passwords.
