Enigmaa

``` Many services ask you to change your password regularly. Random ones are hard to remember, and I had run out of new ways to rearrange my own, so I made Enigmaa.

Fill in a few words only you know (the parameters), pick a date, and Enigmaa works out the password for that day. The same parameters on the same day always give the same password, so even if your records are lost you can work it out again. To change a password, pick another date or swap the order of the parameters and the result is completely different.

• Each password is 11 letters and digits plus 1 symbol of your choice, placed at the start or the end. If a site does not accept symbols, simply leave it off • Add as many parameters as you like, in any language. A different order gives a different password • Save a password with its date and parameters to your history and open it later • Four shapes work as categories. You can rename them; they only help you tell things apart and do not affect the password • Locked with a master password, with Face ID as a shortcut and a recovery key as a backup • The interface is in Traditional Chinese and English. It follows the system language on first launch and can be switched in settings • Copied passwords are cleared from the clipboard after 60 seconds, are not passed to your other devices, and the app locks itself as soon as you leave it

All data stays on your iPhone, encrypted with your master password. There is no account, no network connection, the developer cannot see any of your data, and nothing about how you use the app is collected.

Please note: the master password you set the first time is the root of the whole formula. Changing it later does not change the passwords it produces, and on a new phone you need to enter that first one. If you forget the master password, the recovery key and the hint answer, the data cannot be recovered.
