Password Strength FAQ
What makes a password strong?
A strong password combines length, uppercase and lowercase letters, numbers, and special characters. The longer and more random it is, the harder it is to crack.
How many characters should my password have?
At least 12 characters is recommended, but 16+ is better. Length increases entropy and makes brute-force attacks exponentially harder.
Is it safe to check my password here?
Yes. This checker runs 100% in your browser. Your password is never sent to a server, so it remains private and secure.
Should I change my passwords regularly?
You should immediately change passwords if a service you use has a data breach. For critical accounts like email or banking, updating them every 6–12 months is a good practice.
