MDA is not just another password manager, MDA's main purpose is to keep available all the information that could so easily become lost or hard to retrieve after your demise or incapacitation. MDA offers real security as your sensitive data is never stored anywhere but on your device, unless you choose to export a backup.
Imagine the scenario where you have had a bad accident and you are in a medically induced coma. Your partner needs access to your bank just so they can eat or they may need to do something as simple as retrieve your clothing from a work locker or to just login to pick up your email. All these things would be difficult if they did not know the right accesses needed, creating even more stress at an already stressful time. MDA fills this gap and gives you peace of mind whilst making their life so much easier.
On setting up an account you must provide details of a nominated person who you will give your passcode to so that they can gain access should the need arise.
