Cos'e' Controllore Forza Password?

A powerful developer tool designed to help you work more efficiently. Password Strength Checker provides accurate results instantly with a clean, intuitive interface. Perfect for developers, engineers, and IT professionals.

Formula

entropia (bits) = Length × log₂(Pool Size)

Pool Size = 26 (lower) + 26 (upper) + 10 (digits) + 33 (special) = 95 max

Score based on: length (50%), case mixing (15%), digits (15%), special chars (20%)

Esempio

The password "Tr0ub4dor&3" scores ~56 bits of entropia (Good). It would take days to months to crack. A better approach: "blue-elephant-dances-midnight" has ~98 bits (Very Strong).

Domande Frequenti

How is password forza calculated?

forza is calculated usando entropia (bits of casualeness), length, character diversity, and pattern analysis. Higher entropia and diverse characters result in stronger passwords.

What is a good entropia score?

entropia above 60 bits is good, above 80 bits is strong, and above 100 bits is very strong. A 12-character mixed-type password typically scores 70+ bits.

Perché la lunghezza è più importante della complessità?

Length exponentially increases password forza. A 20-character lowercase-only password (95 bits) is stronger than a 10-character mixed-type password (66 bits). Length always wins.

Is this strumento storing my password?

No. All analysis happens in tuo browser. For security, consider typing a similar password rather than tuo actual one.
