About Passphrase Lab
Passphrase Lab checks a password on your own device and shows the working behind each result: the count, the estimate, the assumptions and the source. It also makes random passphrases.
It never says that a password is safe. It reports what each check found, and what each check cannot see.
How each check works lists every source and grade.
