"Memorandum - Password Manager" is a memorandum tool that can record information that must be remembered, including IDs and passwords that are required in various situations. Just remember the 4 digit number to access the app. You can manage information that continues to grow by just that. Any information such as SNS, net shop, homepage, certificate, credit card, bank, game, app, mail, network etc can be recorded simply. Since iCloud is compatible, even if you have multiple devices, you can share the same information and you can use it very conveniently. (You will need to use the same PIN code when sharing data via iCloud on multiple devices) It is also possible to retrieve data for backup. You can prepare for the case of getting by merely acquiring the files in the shared folder through iTunes and backing up entirely. The reason for developing this application is because there was no application that will explain where important information is stored. This application was born because the developer wanted an application that can be recorded with peace of mind. In addition, we assume that no responsibility will be incurred in us any trouble using this application. It will be encouraging if you can highly appreciate the ability to continue developing and improving functions in the future.
