A couple of weeks I’m using Franz. Franz is a portal for all your social media accounts, like Skype, Facebook Messenger, WhatsApp etc.
When you – like myself – use multiple cellphones, twitter accounts etc. it’s easy to open them all in the same window. For example, I have 2 whatsapp accounts, telegram, but also my private email in one view. I thank it’s a great solution for all those accounts. You don’t give the credentials to the Franz app although, you still authenticate to the (web)apps you normally login to. Franz is only a webportal/viewer.

And yes.. Franz is free. 
Sounds good Xander! A very usefull tool 🙂
