This reminds me of my bank, where the password can only be 12 characters long and only alphanumeric, but they compensate with "security questions", "Web pin" and SMS auth, where I would be perfectly content (and save time) sec-wise if they would just let me use my normal >24 character password scheme, and maybe the pin on unfamiliar computers. Oh, and their mobile app? Only requires my 4 number debit pin and no username. I'd be much more worried about losing my phone that's preauthed than someone scanning my brain and discovering the password. On May 12, 2012 7:59 AM, "Michael J. Gray" <mgray () emitcode com> wrote:
