Frequently Asked Questions
What makes a password strong?
A strong password has sufficient length (12+ characters), includes uppercase and lowercase letters, numbers, and symbols, avoids common patterns, and has high entropy.
How is password strength calculated?
We calculate strength based on length, character variety, entropy, and absence of common patterns. The score ranges from 0 (very weak) to 100 (very strong).
What is password entropy?
Entropy measures the randomness and unpredictability of a password. Higher entropy means the password is more difficult to crack through brute force attacks.
Is my password data secure?
