Strong passwords are one of the most important defenses against hacking and unauthorized access. Using a secure and unique password — combined with two-factor authentication — significantly increases your digital safety and reduces the risk of credential theft. If your password appears weak in the checker, use the generator to create a stronger version and update it across your critical accounts such as email, banking, and cloud services.
To stay secure, avoid reusing passwords, change them regularly, and store them in a trusted password manager. Your cybersecurity starts with strong authentication — and this tool helps you build it step by step.
