Folks, you really need to rethink your security edge cases... This is ridiculous.

I recently realized that I needed to update my phone number on my Airbnb profile.

Then I got the "this number is already in use" message.

Then I logged in using the number to make sure I didn't have a secondary account... Only to find myself in the homepage of ANOTHER PERSON WHO HAD THEIR FINANCIAL INFORMATION IN THERE!

Seriously????!!!!!

What.The.Hell.

But did you recently get that phone number ?  How did the Airbnb confirm the phone number if it was in your possession  in order to have someone else put their financial info?
