One of the key challenges to mobile and web payments is being able to carry your payments information across mobile platforms and websites, including your credit cards, as well as shipping and billing information. Apple and Google are trying to do this on mobile phones with their respective mobile payments services, Apple Pay and Android Pay. Now PayPal has introduced an attempt at a universal wallet called One Touch payments.

With One Touch, you need only log in once with PayPal to pay for goods across different mobile apps and websites. On Monday the company touted the success of the service, claiming that more than 10 million consumers have enabled One Touch in over six months.

PayPal said that more than 1 million merchants around the world allow people to pay with OneTouch, and PayPal is processing millions of One Touch transactions each month, according to their senior vice president of product, Bill Ready.

Here’s how One Touch works: If you log in to an e-commerce site or an app and use PayPal PYPL , you’ll be prompted to enter your username and password to use your credit or debit cards on file. After that log in, any other attempt to purchase an item on the web or within an app using PayPal will proceed with a one-click confirmation of the purchase.

Because users don’t have to keep re-logging in, they end up spending more and are less likely to abandon their online shopping carts, PayPal has said.

Digital payments, especially on mobile, is an area where technology companies and retailers are trying to get both consumer attention and their dollars. Forrester, the market research firm, forecasts that mobile payments will top $142 billion by 2019, up from $67 billion this year. Walmart WMT also just announced its mobile, in-store payments service, Walmart Pay. Apple AAPL just inked a deal to bring Apple Pay to China, and Google GOOG is expanding Android Pay internationally, launching in Australia in 2016.
