Is a 12-character password secure enough?

A 12-character random password with mixed case, numbers, and symbols provides approximately 75 bits of entropy, which is very secure against brute force attacks and meets most security requirements.

Why choose 12 characters over 16?

12-character passwords offer a balance between security and usability. They're strong enough for most applications while being slightly easier to manage if you need to type them occasionally.

What characters are included?

Our 12-character passwords include uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%^&*). This full character set maximizes security.

Can I use this for sensitive accounts?

Yes! 12-character random passwords are suitable for most accounts including banking, email, and social media. For maximum security, consider 16+ characters.

Do you store any generated passwords?

No! All generation happens in your browser. We never see, store, or transmit any passwords. They disappear when you leave the page.
