A disgruntled Lloyds TSB customer who used the phrase 'Lloyds is pants' as his account password, saw the banking giant change his password without his consent.
Steven Jetley changed his password following a dispute with the bank over travel insurance. However on trying to access his accounts he discovered the password had been changed to 'No its not' by a member of staff.
Jetley tried to return to the original password but was told it was "inappropriate" as was his second choice, 'Barclays is better'.
Jetley also claims he is still trying to find a password that meets the bank's criteria.
"The rules seemed to change, and they told me it had to be one word, so I tried 'censorship', but they didn't like that, and then said it had to be no more than six letters long," Jetley told the BBC.
Lloyds TSB said it had apologised to Jetley and terminated the employment of the member of staff responsible.
