PersiPass 作者： OWA Pro

Forget about vulnerable password managers and cloud password storages.
PersiPass is the storeless password manager.
It does not store your passwords somewhere.
That means no one can steal what has not stored anywhere.

PersiPass provides a very strong persistent password for you, based on URL, specified password size, expiration period, optional username and a secret encryption key.

The secret encryption key is not exposed to the end-user, but you can restore it by using special mnemonic sentence (a secret phrase) -- a group of easy to remember words.
