Frequently asked questions

What is a memorable passphrase?

A memorable passphrase consists of several random words joined together (e.g., "Apple-Cedar-Chair-Dream"). According to security guidelines (like NIST), these are often easier for humans to remember while being mathematically extremely difficult for computers to crack.

What is entropy in passwords?

Entropy measures the unpredictability of a password in bits. Higher entropy means it would take much longer for a hacker to crack via brute-force or dictionary attacks.
