security The Anatomy of a Strong Password
Strength isn't just about length—it's about character diversity. A truly secure password mixes uppercase letters, lowercase letters, digits, and special symbols. This creates a massive search space for any potential hacker, making it exponentially more difficult for automated tools to guess your credentials.
Frequently Asked Questions
Is it safe to use an online generator?
Yes, when it's built like ours. Everything happens on the client-side. We do not store, log, or transmit any passwords generated here. For maximum security, you can even disconnect from the internet after the page loads and it will still function.
How long should my password be?
For most consumer accounts, 12-16 characters is a solid balance. For sensitive accounts like banking or primary email, we recommend 20+ characters with all complexity types enabled.
