One in four young adults is still using the bank account chosen for them by their parents when they were a child, according to new research.
Meanwhile, almost a quarter (24%) of young people believe that tech companies such as Google, Apple and Amazon could do a better job than a traditional bank in offering financial products in the way their generation needs them, according to the findings from uSwitch.
A further 18% would place supermarkets above banks for offering relevant products for people their age.
When asked why they had chosen a particular current account to be their main account, 26% of 18-to-34-year-olds chose the option: "My parents set the account up for me as a child, and I've just stayed put," the survey found.
Just under one in three (32%) of young people surveyed believe their bank offers products to help them deal with the financial challenges faced by their generation.
One fifth (22%) of those surveyed had never deposited a cheque and 62% had never used their bank's mortgage services.
Instead, the "millennial" generation is looking for simple help with their short and long-term financial goals, the findings suggest.
The wish-list among younger customers includes help with how to improve their credit history, clear information on savings and pension products, as well as general help on how to better manage their money.
A new seven-day switching service was introduced across the industry in 2013 to make it easier for current account customers to ditch their old provider and switch to a new one. Figures recently released by Bacs show that more than 1.1 million current account customers have switched to a new provider in the last year, marking a 4% increase on the previous 12 months.
Nicolas Frankcom, money expert at uSwitch.com said: "The banks must work harder, with more innovation around relevant products and services if they are to attract the custom of this generation. If they don't, someone else will."
More than 1,000 18-to-34-year-olds took part in the research.
