Guarded Key is the most secure password manager which uses encrypted database to store all your online identities, bank accounts, credit/debit cards, contact information, product codes (software activation keys, serial numbers, registration codes). Optional iCloud - Synchronize iPhone/iPod/iPad and Mac OS X devices. FREE VERSION: Never expires, no ads, up to 32 records in the database (8 passwords + 8 cash items + 8 contacts + 8 products) FULL VERSION: Never expires, no ads, unlimited records in the database Demo database: load it and see Guarded Key in action! DATA MANAGEMENT Encrypted database is stored on your device. Use cloud service to enable database mirroring and synchronize data on all your devices from the cloud. The database uses very strong encryption, so database in the cloud and upload/download is absolutely safe. Local database on the device is the primary data source for the app. If the cloud service (or the internet) is not accessible for any reason, the app works with local database and you have your data under total control (unlike online password managers). Transition between offline and online is made seamlessly without any user interaction. You can always backup/restore data through iTunes on your desktop computer. DATA SECURITY Each record in the database is encrypted with 4096-bit key and 8 layers of encryption consisting of different encryption standards (AES, Triple DES, Blowfish, Twofish). Encrypted database can only be accessed after providing username and password (this is the only password you have to remember). Database is protected so well, that breaking 10 character password would take on a personal computer 8 billion years.
