I worked for a personalization vendor a few years ago and was on an engineering team that built a feature like this. It was ... a major headache, and I don't think anyone was ever completely comfortable with the security implications. So I wish the team good luck, and especially with issues like: * A/B testing. How can you ensure that what your clients are seeing is the same thing you are seeing? Maybe you've been as…

In our experience, this tends to be where A/B testing group identifiers are stored. But, if it was on something like the IP, then, yea…

So you keep client cookies and auth tokens… somewhere?

There is a payment provider in Europe that has become rather popular, who implement "instant" payments by asking for your online banking credentials... Security best practices always go out the window when they interfere with the business case.
