A man whose phone was stolen last summer said the bank refused to help him when thieves accessed his apps and took £22,500 from his accounts.
Jacopo de Simone's mobile phone was taken from his pocket, and was locked and password protected. But within hours his bank accounts had been drained. He said: "I found both my current account and savings accounts had been drained of £22,500. I was completely shocked. I didn't know how this was possible.
"I don't access my phone using a pin code - I use facial recognition. My Barclays pin is different to my phone pin and they'd need to have both of them."
