The Fraunhofer Institute for Secure Information Technology in Germany has released a unique password-storing app for mobile phones.

"The application, MobileSitter, will store passwords, PINs (personal identification numbers) and TANs (transaction authentication numbers)," writes Computerworld's Jeremy Kirk. "Those secret codes are encrypted and then revealed by entering a master password."

"The MobileSitter... will always return an answer regardless of what master password is entered," Kirk writes. "If your debit card PIN is '5555' but a wrong master password is entered, the MobileSitter will decrypt a value based on that wrong password, such as '8901.'"
