Features:
    1. Manage digital passwords, digital locks, how to play with you
    2. It can automatically generate passwords, which is very suitable for people who are too lazy to think about passwords (of course, you can also specify passwords)
    3. Support multiplayer mode, like I will use to remember my dad's password, otherwise I really guess every time I feel tired
    4. History, fear that if the key is wrong, you will need to use the old password to recover.
    5. The backup password is very simple. After changing the phone or uninstalling it, you can quickly and painlessly recover from the photo album.
    
safety:
    1. Process encryption (including calculation processing, and page switching...etc., both encryption and verification)
    2. Store data encryption (if you can see the data, it is basically random)
    3. Incomplete data (Basically stored data is incomplete, so you need to crack the entire program to steal your data)
    4. Data feeding (in addition, a lot of fake data is added to increase the difficulty of cracking)
    5. Anti-reverse engineering (to prevent the code from being pushed backwards from the App, increasing the difficulty of decoding the code)
    6. Connection restrictions, no server, no third party, all functions will not use the network
    7. Please save your backup data yourself, or manage your own peace of mind, right?
    8. If the system detects someone trying to crack, it will delete your data directly, so please remember to have the habit of backup.
    9. If the login fails too many times, it will limit the time of the next login.

other:
    1. Design, function and operation are simplified, the goal is simple and good operation, on the other hand, it is also spent on safety.
    2. No charge, but there will be an advertisement when you log in, just give me a reward. XD
    3. I think the less people use security, the higher XD
    4. Like important financial passwords, personal advice still remembers the best...
