Are you sure that it's from Jaxx?
I have installed Jaxx android app before and it didn't give any password, you will only have a 12-word Backup Phrase like in other wallets
(refer to the link given by NeuroticFish). Without it, there's no other way to restore your wallet.
Moreover, please keep in mind that info, including but not limited to passwords, backup phrase, and private key should not be shared in public for security.
