The Jaxx ETH Wallet address supports any ERC20 token. However, we are selective about which new projects we support in Jaxx so not all of the tokens are available as a wallet in Jaxx. For the ones we haven't directly integrated into Jaxx yet, there isn't a way to manage them through the Jaxx Wallet app interface.
Rest assured you can store those tokens in your Jaxx ETH address safely, but if you want to transact them, you will need to export your Jaxx ETH address Private Key (MENU > Tools > Display Private Keys > (I UNDERSTAND) > Display Ethereum Keys) and import it in another wallet that supports that tokens. You will be able to transact it from there.
If there is a token you would like to see supported in Jaxx then please do add your voice to others on http://Twitter.com/Jaxx_support or http://reddit.com/r/jaxx or by mentioning it when submitting a New Support Request (top right button) and choosing New coin request in the Token you are inquiring about selection.
We are listening and your request does help us decide which projects we should dedicate our time and resources towards supporting.
Disclaimer: Please make sure you do not share your private keys with anyone, including Jaxx User Success team, as if someone gains access to them, they will also be able to manage your digital assets.
