Frequently Asked Questions
What makes a strong password?
A strong password is at least 12 characters long (16+ is better) and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols. It should not contain personal information, dictionary words, or predictable patterns.
Should I use a password manager?
Yes! Password managers allow you to use unique, complex, random passwords for every single account without needing to memorize them. You only need to remember one strong master password.
Is my password safe on this tool?
Yes. Password Strength runs entirely in your browser. Your password is never sent to any server, stored, or shared. You can even disconnect from the internet while using it to be sure.
How often should I change my password?
Modern advice is to only change passwords if you suspect a breach. Forced regular changes often lead to users choosing weaker, predictable passwords (e.g., changing 'Pass1' to 'Pass2').
