A new report from Australia-based telecommunications provider Telstra reveals that the majority of U.S. consumers who use mobile banking want their devices to recognize them via biometrics such as fingerprint and voiceprint, rather than passwords and usernames.

"What we uncovered is that when it comes to mobile banking applications, consumers no longer believe in just the safety of passwords and usernames," said Rocky Scopelliti, global industry executive for banking, finance and insurance at Telstra. "Instead, two-thirds of U.S. consumers think that using biometrics — such as voice, fingerprint, iris and facial recognition — would be more secure and help reduce the risks of fraud.

"In fact, one in four U.S. consumers would even consider sharing their DNA with their financial institution, if it meant it would make authentication easier and their financial and personal information more secure," he said.

Less than half of U.S. consumers were "very satisfied" with their institutions' authentication methods, the study found, USAA customers were the most satisfied with the identity and authentication methods offered and are the most likely to recommend them.

"With our consumption of financial services intrinsically linked with the mobile device, our mobile identity is the key to unlock trust with our service provider," Scopelliti said.
