Perhaps if you like your financials online. Go for it. Just understand that online banking has it's own issues.
I locked mine down after someone fraudulently accessed my bank accounts online. And, kept getting into them by using my information and locking me out of them (the most minor part of ID Theft mentioned previously) It's so secure now, that even if you walk into the bank in person, look like me, carrying my ID card, and the teller knows me and recognizes me, they will not do a thing with my account. Even the Manager won't release anything to me, and we've known each other personally for more than 40 years. There are other methods I've implemented that must be in place in addition to my physical being, ID card, signature, and being recognized... that doesn't even get you close to my money.
Yeah, it's locked tight, and no I wouldn't do anything with a cell phone to manage my money. There is no Internet access to my accounts.
If you've only been the institution who holds your money once in your life, then you've got nothing. Any random person could walk in there, know your information, and walk out with your money. That's exactly why I deal local, with people who know my face, who will implement special practices for me because they know me, and will personally protect my interests.
You wouldn't believe how easy it is to manage your bank account without any identification if you know all the information. With mine, you won't touch my accounts even if you have my face.
