I signed up with Viglink yesterday, adding the email address for my PayPal account, and because I was lazy, I used the same password as my PayPal account (a big no-no!).
Maybe it's just "coincidence" but I just had an unauthorized purchase through that PayPal account...but luckily PayPal thought it was fishy and reversed the payment before I even knew what had happened.
But I needed to go through a few steps with PayPal, including changing my password and updating other security measures before I could access the money in that account.
I don't know if there's a security issue with Viglink, but that's the only new change I've made that includes PayPal information. I've changed my pw for Viglink too.
