Card readers, password checks and number fobs are just a few of the new technologies that online banking can use but some experts fear that too many technologies may make customers wary of online banking.
Garry Sidaway, from Tricipher, an ID and authentication, told the BBC that masses of security checks could make customers nervous.
"The banks have to make this channel secure but there is crumbling confidence in it," he said.
Lloyds and Barclays have used generating key fobs and chip and pin card readers.
Another expert, Andrew Maloney, financial services market director at RSA Security, said banks were aware that their efforts could turn customers away and noted that it was not just a case of combating fraud but a case of keeping customers happy.
But the security technologies appear to be working, statistics in October stated that online banking fraud for the first six months of 2007 was down 67 per cent over the previous year.
