## Company

Launched in April 2010, AliExpress is a global retail marketplace targeted at
consumers worldwide. The platform enables consumers from around the world to buy
directly from wholesalers and manufacturers in China through access to products
at competitive prices. AliExpress is a business within the Alibaba Group.

## Challenges

Shoppers from over 200 countries and regions have downloaded the AliExpress app
or used its desktop and mobile websites. In order to make a purchase, users are
required to enter their account information each time, which can be unpleasant.
In addition, users sometimes forget their login information, requiring them to
leave the app and reset their passwords. This is especially problematic when
moving cross platform in the middle of a purchase.

## Solution

With Smart Lock, AliExpress was able to improve the user experience in their app
and websites: it's faster for users to login and start the shopping journey,
users do not need to constantly remember their passwords, and users can be
automatically signed in when moving between platforms like Android and Chrome
web.

Smart Lock on Android prefills 3 out of the 4 required onboarding fields (Email,
First Name, Last Name), reducing manual typing errors. 50% of all new users on
the native app are signed up with the hint selector dialog, and 95% of users
have saved their credentials to Smart Lock for seamless return next time.

After implementing Smart Lock on Chrome with the Credential Management API,
there was a 85% drop in failures during sign-in and a 60% decrease in time spent
signing in.

It was easy for AliExpress to implement Smart Lock. It took only one engineer
and about three days to implement and test the API on Android and a similar
amount of effort on Chrome.
