Frequently Asked Questions

How many characters should my password be?

Security experts recommend 8 characters as the minimum, with 12 characters or more for important accounts. PassCraft lets you generate passwords from 8 to 12 characters (or any length you choose) in seconds.

Is an online password generator safe to use?

PassCraft is safe because it runs entirely in your browser using the Web Crypto API. Unlike other tools, your passwords are generated locally and never transmitted, stored, or logged on any server.

What's the difference between an 8-character and 12-character password?

A 12-character random password is approximately 500,000 times stronger than an 8-character one due to the exponential increase in possible combinations. For most accounts today, 12 characters is the recommended minimum.
