Just bought and have only tested functionality sending secrets to myself. But this is far more professional that sharing passwords or other secrets in WhatsApp and of course much more secure than email. The problem I always have is a recipients ability to deal with any more secure solutions I put in place - and the overhead/friction it adds to clients (or friends). InPrivy removes all of this, and provides a decent audit trail so you can see whether secrets have been viewed etc. Nice that you can add your own branding and customise messages etc.

I also love that you can upload and share documents. I run a small agency and one thing I'm considering is using In Privy as somewhere to store emergency instructions for my clients (i.e. how to access / recover their sites if I'm incapacitated). This would only be a fall-back - and I may decide it's too much of an overhead to maintain. But worth thinking about.

Bottom line, I was impressed enough with the simplicity and perceived value of InPrivy that I've taken time to write a review. It also seems like great value for money.
