Barclays has announced the introduction of its voice security technology to all personal banking customers, according to a company press release.

"Barclays is constantly looking at ways to improve services for customers and make it easier for them to get things done quickly; this is the perfect example of technology that does exactly that," Steven Cooper, CEO of personal banking at Barclays, said in a statement. "There's no need for customers to change how they bank with us, or in fact do anything differently at all – just continue to use telephone banking in the same way. We're committed to providing options so that our customers can choose how they want to bank with us and this is the latest iteration of that promise."

The technology identifies the caller based on their voice. The identification method removes the need for security questions and passwords, according to the announcement.

"We can all relate to the frustration of forgetting a password at the crucial moment," Cooper said. "Voice security can cut out that part of the call completely and, unlike a password, each person's voice is as unique as a fingerprint."

Barclays first tested the technology in 2013, but has not announced when it will be available for corporate and business customers, according to the announcement.
