Passphrasen-Stärkeprüfer

Estimate length and word variety without sending the phrase to a server. This is educational feedback, not a guarantee.

So funktioniert die Einschätzung

The checker looks at length, apparent word count, repetition, and basic variety. It does not know whether your phrase appears in a breach list, quotation database, or attacker dictionary. A long famous sentence can still be predictable.
