PayPal Tuesday (April 30) started pushing its new online login system, called Log In With PayPal. The essence of the new program is pretty much "autofill," in that it autopopulates the forms of any e-tail site that is part of the program. It also allows PayPal users to login in with their PayPal credentials—which is not new—a move that is intended to make it less necessary for shoppers to keep track of dozens of password/login combos for all of their favorite e-tail sites.
From the shoppers' perspective, that single login is not that exciting, as most have been doing a very insecure replacement: using the same login/password for those dozens of sites. In effect, that's what PayPal is doing. The security impact is that if there is a breach—at PayPal, at that shopper's computer, elsewhere—that password can now be used to access all of those sites. At least that's the hole until PayPal is contacted and the password is shut down or changed.
Of greater potential benefit, though, is PayPal's mobile component. There are a very large number of low-cost programs today that will autopopulate user information (address, name, payment details, etc.) for desktops and laptops. But very few such programs today exist for mobile. PayPal's ability to fill out the mobile forms may make a huge difference in purchase completion.
Although mobile devices are used extensively for shopping and searching, most of those transactions stop when the item is placed in a shopping cart. That transaction is often completed later on a laptop/desktop. That's because typing so much information into such a small screen is unpleasant, and doing so in a public area (think subway, plane, waiting room) can be awkward. PayPal's mobile autopopulate function could make a meaningful difference with mobile checkout.
On the down side, there's data control. This will deliver to PayPal a huge amount of data, data that PayPal has said before it will share with retailers. That's great news if that means sharing with your team. That's horrible news if it means sharing with your rivals. The reality is that it means both.
