JPMorgan Chase has added fingerprint authentication for customers on Android devices.

Chase implemented the feature as part of a software update to its Chase Mobile app released Monday. Customers can use fingerprint verification to sign in, and certain functions within the app may still require users to enter their password for additional authentication.

In June 2015 Chase became one of the first large U.S. banks to enable the feature on its iPhone mobile app when it added Touch ID authentication for iOS users.

Android opened its fingerprint authentication application program interface to developers with its recently released Marshmallow operating system. That move also allowed Bank of America to make the same offering to Android users last week. Previously B of A’s fingerprint scanner was available only to Samsung users.

Chase’s active mobile base totaled about 23 million in 2015, a 20% increase from the previous year, it said in its annual report this month.

Chase has also allowed customers to view balances without entering a password since late 2014.
